I know there are several billion videos like this already out there, but I wanted to do my part and add yet another piece of perplexing madness to the teetering mountain of insanity. My focus was mainly on the music, but the animation ended up being a lot of fun too.
WARNING: There's a section at about 1:10 that has a flashing strobe effect. If you suffer from epilepsy, you may want to steer clear.
***EDIT - This upload ended up being a little choppy. You can watch a much cleaner version here on Newgrounds, in its original flash format, as nature intended: http://www.newgrounds.com/portal/view/606000 ***
