Random Randbow Path (Resized)

Added a fade and blur.
Created by: PESakaTFM
Inspired by http://www.loadedrecords.com/assets/plecs.swf
I don't know who made that one, but I kind of liked the idea.
Mine is different from the original that inspired me (I assume) 
because I draw everything to a bitmap instead of using (and reusing) 
lots of MovieClips.
I'm hoping this will give people more flexibility for effects.
