Prank your friends! Make screenshot of your applications icons, then run app, chose that screenshot in settings and tell them you have images on your iPhone, then hand it to them...
When they touch the screen, the icons will fall to the ground.
A simple but fun app :) Get it before your frineds get you!
Also you can choose screenshot from your current desktop for more reality, or take any picture and solve a "puzzle".
- Real gravity.
- Try to blow images out from screen.
