Kludge coming to iPhone!
I'm developing a master mind clone - Kludge which is due to be release by mid April with my multi-talented partner whose a game artist and a game designer rolled into one.

We are putting the players into a futuristic setting where we try to make them think they are trying to hack through a futuristic and high tech computer. Pretty cheezy huh.
There's no 3D here. Just using Core Animation for various twist and squeezing animations (no CALayer) and UIKit for displaying all the images. A whole lot of UIImageViews instances!
