I created this using action script I used the law of Math. and the law i used was the the Pythagorean theory basically means that when i leave a given point it get smaller and as i approach the center again it gets bigger thus increasing the volume of the music. It made allot of sense when i first did it lol.
Good idea
I'd like to use something like this on one of my band webpages. It's really more of a gadget than a game. Perhaps you could channel this into a dj game where you can mix tracks and scratch. Or maybe que loops by holding down keys. The application is there, you just have to find it.
