Hopefully someone can point me in the right direction... I remember browsing the web a few weeks ago and saw a video/demo about an app where you pick a brush or design and then with your mouse just move it and the app creates an abstract drawing. Say a tree trunk with branches and leaves. You just start on the bottom and move up and it draws an abstract tree going in all types of directions. If someone knows what app I'm talking about I would greatly appreciate it. I couldn't remember if it was a standalone app or an add-on like a brush for photoshop/pixelmator. Thanks!
