I don't remember who originally posted this example, but Iit and decided to work on the Multitouch implementation for it - after two night and 50 builds I got something VERY responsive to the location according to playfield as well as size of player fingers (I'm fat so my ones are big and they never are so close to each other as they should be!) so feel free to share and comment.
Also there is a Keyboard version for those without iOS runtime but with Multitouch object.
