A simple video game designed by a 14-year-old school kid is taking the world by storm.

Bubble Ball is a physics-based puzzle game that has been downloaded by more than two million iPhone users.

It became the top free application on the Apple store. But it hasn't been designed by a team of highly paid experts - it is the work of Robert Nav, a teenaged schoolboy.

Nav's game even outsold the adventure game Angry Birds. Since its release on December 29, Bubble Ball's success has become astounding, the Daily Mail reports.

Adding to Robert Nav's glory is the David versus Goliath nature of his victory. While he designed Bubble Ball in his bedroom in Spanish Fork, Utah, Angry Birds was developed by 17 professionals in Finland.

The rules of Bubble Ball are simple - players must move a small blue ball from one side of the screen to the other by steering it around various obstacles.

Robert was encouraged to try his hand at programming by a friend who noticed how much he liked his iPod touch. Robert released Bubble Ball through his own company, Nav Games.

Websites that changed the world

Ever since the internet came into our lives, we have come across many websites in one way or the other that have influenced us a lot. They have such a deep mark in our day to day life that we can't even think of a world where they don't exist. By changing our perspective towards anything we see, these websites have made such a huge impact that they have changed the world forever. Listing here are the top websites among them.

1. Google:

Founded by Larry Page and Sergey Brin in 1998 as an advertising company, Google today commands the largest internet search engine in the world. It has turned out to be a gigantic empire and is branching out into parts like email, news, price comparison (Froogle), cartography (Google Maps), literature (with Google Book Search), free telephony (Google Talk), and Google Earth, an incredibly detailed virtual globe. So far it has been able to have such an impact over people that its name is listed as a verb in the Oxford English Dictionary. To be honest, there is nothing much to say about Google. Google speaks for itself.

2. Wikipedia:

When Jimmy Wales founded Wikipedia in 2001, he hardly thought that his creation will one day be considered as one of the most trust-worthy sources of information. What has made this free online encyclopaedia such a big success is that, it is open to everyone to read, and also to edit. Its 17 million articles have been written collaboratively by volunteers around the world, and almost all of its articles can be edited by anyone with access to the site. Today, Wikipedia is attracting 2,000-plus page requests a second.

3. Facebook:

Who thought that a site to connect students of a university with each other will become a tool that every internet user uses? But this is the story of Facebook, the most popular social networking site today. Facebook was was co-founded as a private company in 2004 by Mark Zuckerberg and classmates Dustin Moskovitz, Eduardo Saverin, and Chris Hughes. With its dynamic development system, almost any application is possible. Facebook therefor has many interesting features like Connect, the Facebook Developer Platform, Facebook Chat and so on.

4. Twitter:

Ever since its launch in July 2006 by Jack Dorsey, Twitter has gained tremendous popularity worldwide and currently has over 175 million users globally. Who is not on Twitter today? Starting from celebrities, to politicians to scientists, everyone has a twitter account and sending and reading messages called tweets. It is estimated that Twitter is generating 65 million tweets a day and handling over 800,000 search queries per day. Most businesses have twitter accounts as well to be more interactive.

 5. Yahoo!:

Started as a hobby by two Stanford University graduates Jerry Yang and David Filo in 1994, Yahoo! today is considered as one of the most visited and popular websites on the internet. On the back of its early success, Yahoo! branched out into email, instant messaging, news, gaming, online shopping and an array of other services. The company is perhaps best known for its web portal, search engine (Yahoo! Search), Yahoo! Directory, Yahoo! Mail, Yahoo! News, advertising, online mapping (Yahoo! Maps), video sharing (Yahoo! Video), and social media websites and services. Although eclipsed by Google, Yahoo! still has its own image among the internet users.

6. YouTube:

Launched in 2005 by Chad Hurley, Steve Chen and Jawed Karim as a user-friendly site to upload and share videos, YouTube has become one of the most popular sites on the net today, with claiming that 100 million clips are watched every day. Starting from homemade video clips to long-lost TV and film gems, YouTube is a place where people can upload and share videos. It has also taken off as a place for amateur film-makers to show off their talents

7. MySpace:

Owned by News Corporation, this California-based social networking site became the most popular social networking site in the United States in June 2006. Although it was overtaken internationally by its main competitor, Facebook, in 2008, based on monthly unique visitors, MySpace is too effective and ubiquitous to ignore. As of June 2010, the social networking site has 66 million users all over the world. One of its interesting features is the ability to upload and listen to music, which has attracted 2.2 million new bands and artists to the site.

8. ebay

ebay was the website that brought the concept of online shopping and bidding industry for the first time. Ever since its launch in 1995 by Pierre Omidyar and Michael Dean Johnson, ebay has turned out to be a huge shopping mall where people and businesses buy and sell a broad variety of goods and services worldwide. It is now a multi-billion dollar business with operations localized in over thirty countries.

9. WikiLeaks:

The recent controversy associated with it and its founder Julian Assange has created a big hype and has attracted attention of the whole world. The website may not that big yet, but the impact that it had on the world is shocking. The website has faced criticism from various governmental and non- governmental organizations, but the fact that makes it so influential is that this site gives you proof and the truth.

10. Amazon:

Starting with an office in a Seattle suburb with desks made out of old doors, Amazon today is the largest online retailer in the U.S. Founded by Jeff Bezos as an online bookstore in 1994, Amazon.com soon diversified, selling DVDs, CDs, MP3 downloads, computer software, video games, electronics, apparel, furniture, food, and toys. Amazon's continued dominance rests on price-slashing which has made it one of the biggest online shopping centers with new and old items available to the users at a simple click of a button.

Basic guitar lessons

We will start by getting you set up on your guitar. If you've already covered holding your guitar, sitting and standing positions and holding a pick then feel free to more on to part 2 of this lesson.

Part 1 - Getting into position

Sitting Positions

There are two sitting positions for holding the guitar; classical and casual.
  • Pick up the guitar and make sure that the guitar body is supported by your leg.
  • Position yourself at the edge of your chair.
  • Ensure that your back is relaxed but straight.
  • Lean the guitar back towards you slightly.

Image of classical sitting position Classical Position

Standing Position

  • Pick up the guitar and place the strap over your shoulder. Adjust the strap so that the guitar is positioned mid-body.
  • Use your left hand to support the neck of the guitar.
  • Rest your right hand over the bridge of the guitar.
Standing position

Hand Positions

It is important that you relax your wrists and hands. Straining them can cause injury.

Image of hand position (rear view) Rear view


On a typical right handed guitar, your left hand will form the chords and your right hand will strike the strings. Fretting is the act of pressing the strings down on the fret board. Here are some tips you will need to know:
  • Short fingernails are essential.
  • Use only the tips of your fingers to press the strings.
  • When making a chord, be sure that each fingertip is placed directly behind the fret. We will cover chords in lesson one.
  • Check each string that it rings clearly and is not muted or buzzing. As a beginner guitarist, it may hurt your fingers to play. This is normal. Every guitarist starts this way for the first couple of weeks. With practice, you will develop guitar fingers (hard skin on your fingertips).

Holding the Pick

Position the pick between thumb and index fingers like in the diagram below:

Time to take a break

Well done, you've just completed the first part of this lesson. Take a few minutes to reinforce what you've just learned.

Coming Up

  • Learn about chords
  • Start using the A and D Major chords

Part 2 - Chords

Now you are ready to start your first theoretical lesson. Your aim in this lesson is to learn the A and D major chords and to introduce yourself to reading guitar tablature. This lesson is very important, so you'll need to stay focused.
Remember! It is more beneficial for you to practice several times during a week than to practice for one long session. This is because your brain processes information in chunks at a time and it can only hold a certain amount in short term storage.
If you take a break between practice sessions, even if it is just 10 minutes, you’ll find that your brain is much more efficient at turning your short term practice into long term knowledge.
Ok, let’s continue with the lesson. Have a look at the diagram below and familiarize yourself with the neck of the guitar.


The guitar neck is divided into what we call frets, making a fret board. Most guitars have around 20 frets. We will focus on the first four frets, also known as the first position.
Image of frets Note: Each string on the guitar is numbered. When you hold your guitar as you would when using the casual playing position, the 1st string is at the bottom and the 6th string is at the top.
Notice also the term, ‘Tuning’ at the bottom of the above diagram. Tuning refers to the notes that the guitar strings are tuned to. In the above diagram, we have given a very common tuning called standard E tuning that consists of the notes E, A, D, G and B. Strings 1 and 6 are both tuned to the note E. The open 6th string is called low E. The open 1st string is called high E as it is two octaves higher than the 6th string open E. We explain notes and octaves in the Jamorama Beginners Course, but for now, you only need to know the names of the notes in standard open E tuning.
Now make sure that your guitar is tuned to standard E tuning (the most common tuning). If you don't know how to tune your guitar, then download our free guide to tuning your guitar from here.
Note: To open the above tuning.pdf file you'll need a copy of Adobe Acrobat Reader. You can download a free copy here.
We will stick to standard E tuning throughout this mini-course.

Introduction to Chords

Now we are going to look at guitar chords. Guitarists use many different chords to make progressions or riffs that can then be used to create songs. If you are not familiar with some of these terms, it’s ok. We will cover everything that I am talking about in good time.
A chord is defined as a combination of 3 or more notes played together. To examine this, I want to take a look at chord diagrams. Chord diagrams are used to illustrate how a chord is played. They are very easy to use because they look very much like the neck of the guitar, in fact, the Jamorama chord diagram is a guitar neck.
Chord diagram You may like to use 'standard' chord diagram when writing up chords on when you practice.
So, now that you know what a chord diagram looks like and how it matches with the neck of your guitar, it’s time to come back to what we mentioned earlier about a chord being a combination of 3 or more notes played together. Numbered finger symbols are added to the chord diagram so we know which notes to play. To start with, let’s look at your fingers.
Each playing finger is numbered so we can then match it on the chord diagram (see below).
Image of numbered fingers And now, let’s look at a full chord diagram. We will use the example of the A major chord:

Chord Diagram - A Major Chord

In the chord diagram below you can see that the A major chord uses fingers 1, 2, and 3. Take note of how this chord diagram looks - we will use this style from now on.
The A major chord is constructed of the notes A, C# and E. We will cover notes a little later.
Image of A major chord Note that there is a red dot marking the 6th string on the above chord diagram. The red dot tells you that you are not to play that string. The sixth string of the A major chord is not played, but you play the rest.
Throughout this lesson series, every chord diagram will be accompanied by a picture of the chord being held on the fret board and video of the chord being played for you to check with. Pictured below is the A major chord being played and you will find the video further down the page.
Image of A major chord being played

Exercise: Playing the A Major Chord

Position each finger with care, according to the above diagram. Make sure that each fingertip is placed directly behind the fret. Firstly, pluck across the strings one by one with your right hand, checking that each string rings clearly and is not muted or buzzing.
Now that we’ve looked at chord diagrams, I want to move on to strumming.

Introduction to Strumming

In a strum there are two types of guitar stroke. They are up stroke and down stroke.
Diagram of guitar srtokes With either an up strum or down strum, brush the strings with your pick, mid way between the bridge (where the strings are pinned) and the end of the neck of the guitar. When strumming a chord make sure you play all the required strings and take note of the strum indication - up or down.

Exercise: Strumming the A Major Chord

  • Carefully position each finger according to the A major chord diagram above.
  • Place each fingertip behind the fret.
  • Pluck the strings 1 by 1 with your strumming hand.
  • Check that each string rings clear and is not muted or buzzing.
  • Practice strumming the A chord with single down strum as indicated below:
Diagram of stroke count Try counting an even 4 count as you strum as this will get you used to playing in time.
Tip: You can watch a video example of the above exercise to see and hear it for yourself.
Try your best to start your strum from the fifth string each time you strum. A major, doesn’t sound bad if you accidentally hit the top string, although if you want your music to sound professional, you’ll want to play this chord properly. Remember to stay relaxed. Your fingers may hurt a little but they will get stronger.
Now that you are playing the A major chord properly, let’s take a look at strumming another chord...

The D Major Chord The D Major Chord is constructed of the notes D, F# (F sharp) and A and is played using fingers 1, 2 and 3:
Image of D Major Chord As with the A major chord: try strumming the D major chord in downward strokes with your right hand.

Video - D major chord
Note: The top two, or fifth and sixth, strings are not played in the D major chord. Make sure that you start your stroke from the forth string each time you strum D major, it doesn’t sound bad if you accidentally hit the fifth string, although as with A major above, if you want your music to sound professional, you need to play this chord properly.
