Here's the flash made out of boredom, actionScript3, FlashDevelop and latest papervision3D version "Great White".
Made in 3 days, yeah!
ATTENTION - THIS FLASH LIKES YOUR PROCESSING UNIT A LOT
If you have don't have dual core CPU hit [f] and [g] keys immediately after the flash starts, that will turn off 2 main filters. Most of the calculations goes to the rendering engine of papervision and if you are getting huge lagg - don't open it again on your actual pc, don't rant about it and go somewhere else to watch the play of colors.
See the help window to configure the visualizer.
There are 5 sample songs so go ahead and play with your 1-5 keys.
Hope you enjoy the show of colors and leave some critique in here (:
If there's some error popping out in a new window - tell me right away.
