One day I was surfing the net trying to find something interesting and outstanding. Eventually I bumped into some interesting projects which uses iPad or iPhone in a very unusual way

I was very surprised to find out this kind of iPad usage

Next thing I was very surprise to find was a guitar amplifier! They even made a separate versions for iPhone and iPad, so you can choose whichever suits you more.

But I was very surprised to see this kind of usage

Very professional and innovative, even the concept behind is very simple

As a conclusion, I can say, sometimes you can get very simple but interesting ideas and create application no one ever created before, but for it you have to believe in your imagination.
