Music responsive 3D game

newton_rocks

Hi guys,

I am game developer but also a music producer so I decided to mix up my two passions and start a new project. A kind of videogame-album "experience" (experience in the sense of "journey" videogame) that will be playable on iOS, Android, Windows, Mac and Unity Web Player.

The main idea is to make a very nice and scifi game art, make 3D objects to be responsive to the beat of the song.

Unfortunately, I don't have money to spend buying 3D models so I was wondering,
Where do you recommend to search?
Is there anything like Creative Commons License community for 3D models?
How do you think a 3D object could respond to a musical element like rhythm, bars, pitch, silences, etc.?

I think you guys are the best people to ask for ideas and tips about.

You can check a very basic demo of the project here:

(You need to install Unity Web Player if you don't have it),Thanks!
