Jason van Gumster mostly makes stuff up. He writes, animates, and occasionally teaches, all using open source tools. He's run a small, independent animation studio, wrote Blender For Dummies and GIMP Bible, and continues to blurt out his experiences during a [sometimes] weekly podcast, the Open Source Creative Podcast. Adventures (and lies) at @monsterjavaguns.
