So I've been trying to learn to draw so that I can make video game art. I even bought myself a neato 6x8" Wacom Intuos3 drawing pad, although it hasn't arrived yet. While looking at reviews of the pad, I stumbled across a review of a product called ArtRage. It's a paint simulator. While there are many paint programs (like Photoshop) with tons of features, none of them really try to simulate the physics of paint. But ArtRage does a really good job at it. They have a free version (with a limited number of tools), but the full version only costs $20! What a deal!
