When I spotted this stand at Macworld, I thought it was pretty ingenious. Ambient Design showcased Art Rage 2, an easy to use painting program that lets you basically treat the screen as a canvas. You can choose to paint with oils, or sketch with pencils, very cool! For the professional user, ArtRage also offers multiple layers for painting, and layered PSD document import and export so you can easily use it alongside your existing tools. This girl in the pic was using the Art Rage 2 paintbrush to paint a beautiful scenery. This program is seriously just like painting, I was very impressed!
