Recently I found out about the Brushes app for the iPhone  (well “recently” meaning back in december of last year), which is not only a fantastic time-waster, but also an actual tool that you can use to make actual art.  On your iPhone.  Wherever you go.  Talk about great for a busride!

The Brushes app is a painting tool with a variety of features, including transparency, a decent color picker, import and export from your iPhone photos, and a bunch of preset brushes that really make this a fun little app.  The new version (which i have yet to download) supports four art layers, not just one, which promises to be entirely TOO MUCH fun… and a serious tool for art-on-the-go.
