Gravilux 2.0 and Gravilux+ AWESOME

The new Gravilux just came out and it is really awesome. Now you can write with stars ("gravitational typography"), and then interact with them, post to Facebook, email, etc.
If you do the in-app purchase to upgrade to Gravilux+, you get a gorgeous music visualizer.
Interacting with Gravilux is very meditative for me. Another beautiful app form Scott Snibbe.
