If you remember THIS, you’d probably use this iPhone app for your own good…
Type’n’Walk, an iPhone software that utilizes the iPhone’s camera so you could text and see what’s infront of you (Next thing we need is an app to play camera-counter-strike… Boy, that’ll be so awesome that I might end up buying one =P)
“camera-counter-strike”
actually, that’s not a bad idea at all! assuming no one made it yet.
