Its kind of meh, not for everyone.

While it does what it says it does, and quickly. I got bored with it pretty quickly. You really need to decide if this fits your personality. Right now it is a bit of a one-trick pony. Audio response would be interesting, or a random mode (bouncing attractor, for instance) might add more life to this.

If you arent a doodler, you might want to pass this one by. But if you are, its not a bad price.
