Each color line has "joints" which you can move, and the line will be bent along those joints. I've been thinking about making this for a while, but decided to do it today. It only took about 30 minutes. I didn't think anyone would look down here! Well, since you did, I guess I'll tell you something cool. You can press space if you like rainbows.
Everything by me. Feel free to use this in your own projects, but please give credit.
