// forked from PESakaTFM's forked from: Random Randbow Path // forked from PESakaTFM's Random Randbow Path // 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. */ package { import flash.display.Bitmap; import flash.display.BitmapData; import flash.display.Sprite; import flash.events.Event; import flash.filters.BlurFilter;
