Naughty Dog Game Designer Douglas Holder has made an interesting little game dubbed ThumbderDome Wrestling.

The game, currently available for PC and Mac, tasks you and (hopefully) a friend to have a thumb war, on the same gamepad. The key thing here is that both players have to utilize their own analog stick and shoulder button, hence the Xbox controller in the above video.
