I liked it, but...
I don't know if it's going to survive portal entry. I gave it a 5, but it had a bad score when I saw the results.
It's an interesting toy at the most, reminiscent of the stuff that was (is?) at the Requiem for a Dream movie page. If you make a revised version of this, you ought to view that web page and see what kind of things they have there in order to make your experiment more interesting.
As it stands, this is all plain shapes and colors when it comes to graphics, but the sound factor and the way the graphics also change when the mouse moves around makes for an interesting timesink.
