Brushes lets you undo or redo virtually an unlimited amount of times, so you don't have to worry about making mistakes. And that brings up another excellent feature--all of your paintings are not only saved as an image file, but each and every brushstroke is also saved as a .brushes file which you can export in the form of a video clip to watch a painting session from start to finish. Just speed up the video playback and you've got a nice movie to share with others.

The only minor drawback to this feature--if you don't have access to a Mac, that is--is the that allows this is only available for Mac OS X. The developer says he is working on either a PC version or possibly setting up a Mac server where people can upload and then convert their .brushes files.

Brushes has a built-in Web server so you can download your paintings directly from the iPhone or iPod touch to your desktop via a Wi-Fi network.

All of these features are nicely wrapped up in a really simple and efficient interface that makes using this app easy and intuitive. I'm definitely impressed with what can be done in Brushes, and it has inspired me to further dive into digital painting. If you're an artist, you'll certainly want this app on your mobile device.
