I've been thinking about making a game to use such mechanics. So I'm interested as well. I'm going to see about creating a quickie on this tonight. If someone doesn't do it first :D
It needs some serous tweeking before it's usable.

however this seems to be the direction to go. I used anywhere touch for now since tracking by checking to see if touch is on top of an object and following, just doesn't work that well. Once you start tracking you need to track by the specific touchID not if it's "inTouch".
