Seems neat, but needs documentation

I can tap and play, and its nice and smooth unlike some triangulated fluid toys. But some features are a mystery:

1. How exactly do you connect the iOS version to the Mac version? I see no mention in either app (nor the developer site) of HOW to do this, only that it can be done.

2. What is "Ambient" mode? The A key does nothing that I can observe.

(Feature suggestion--some kind of tilt senitivity option. Even for this Mac version! I have seen Mac programs respond to tilting a laptop.)
