Artrage: the world's greatest paint simulator

I think when you first look at Artrage, you'll think "this is just another paint program". However, you'd be wrong. I dont even think of it as a 'paint' program at all in the traditional sense. This is more of an amazing paint and other media simulator. Just try out the paintbrush and change some colors - smearing them around - and you can see how the application is actually simulating the physical properties of the liquid paints. Colors smear together realistically, your brush 'runs out of paint' in a realistic fashion. I can only imagine how cool this application works with a Wacom tablet. So, if you have a kid who's artistically inclined, this is a must download. The killer feature for me is the fact that you can 'trace' a background picture and have the tool that you are using automatically (optionally) pick up the color (eyedropper fashion) from the background image. Beautiful!
