On and On: Music creation...in three dimensions!

I'm almost done with my penultimate semester of undergrad at the University at Buffalo and, as such, I've been finishing up some projects this week.
 
Here is my final project for my Virtual Worlds class, made with Unity.   It's called On and On... and the title refers to the Tenori-On, a piece of hardware for making music designed by the dude behind Electroplankton, Toshio Iwai.
 
If you like making music, you'll probably dig it.  If you like games, you could very well dig it as well.  It controls like a first-person shooter; tastes like music!  Er, sounds like music. 
 
Something. 
 
Anyways, after this semester I'm going to work on getting it on the iTunes App Store.  If you want to know when that's done, throw me a PM with your e-mail address or something and I'll keep you up to date. 
 
Edit: It's totally on the App Store now!  Right here.
