Graviboard is a tweak for your iDevice that adds a little bit of fun to your springboard. You can set up an activation method, activate it, and your icons will go all over the place... or no where. You can set different types of gravity to add and even choose to fling your icons at each other.
If you have ever seen that video where the Windows icons attack each other, its kind of like that. This tweak is great fun but comes at a steep price of $2.99. Check out Graviboard in Cydia!
