I was thinking that it would be cool if whereever you touched on the iphone or ipod touch screen, it would show where you touched...Just like in the iPhone ads where it shows a grey circle where someone is "touching" the screen.

If you dont know what i mean, i am talking about when Steve Jobs does presentations with his iPhone and it comes up on the screen behind him and you can see where he is touching the screen via grey circles where he is touching the screen.

If anyone could implement this...THAT WOULD BE GREAT
