Note that I haven't tried the sheep application.
But I have a small general request for games using the accelerometer: It would be good to have a way of defining 'origo', i.e. where the reference is, in order to easily change between playing the game sitting upright vs. playing when on the couch.

It's because I found that it's not really possible to play bounce evolution while on the couch (the squashing apples part. The race part works fine because it doesn't care (much) about forth/back, only left/right).
