The GIMP

Someone in my office is newly on a Linux system gave the GIMP a whirl.
Much to his surprise he's enjoying it, he even finds it moderately intuitive actually. While he's had experience with art programs before and is a bit on the techy side of things, the speed in which he could see what was going on was actually a much short curve than what he'd experienced in most art programs.

While it has only been a cursory use and review, the program looks promissing for smaller projects and possible automated image work implementation.

Could use some better marketing though.
