The only improvement I'd make to this app is to allow a recording feature so you can keep the kaleidescope changes as they happen. Maybe it is there, and I haven't found that little utility yet.
It really is a nifty little app! And only 99 cents for hours of entertainment! My husband was so impressed, he had to get a copy, too. And a few of my friends, too!
