Some time ago I submitted Your Face to newgrounds. It wasn't a big hit here, but worldwide mochibot counts a 16 million klicks.
With a small team I'm beginning to develop for the iPhone now. And we decided to port some of my flashgames to this nice and shiny device. we said: start simple! Your Face is quite simple, no 3d-graphic-high-end-plastic-shit needed, just pencil drawings and two game modes.
Well, just take a look at the flash version and you know what to expect from the iPhone app. Instead of the webcam you can use the phone's camera. pinch-rotate-zoom the portrait to the correct position and decorate it with crazy facial parts -- and instead of printing you can save the pic and send it to your mom or whatever!
So here is the link: Download Your Face on the App Store
PS: which of my games should be next?
