Rocketman has been working lately on an impressive online comic using Blender and several other open source programs. The comics follow a small group of robots, throughout several humorously entertaining sketches.
"Everything is done exclusively with free software. The characters are modelled and rendered in Blender, with layout and speech bubbles in Inkscape and image editing in GIMP- all under a flavor of Ubuntu Linux. Hell, I even wrote most of the html code (poorly) in Vim!"
There are currently 19 comic strips and Rocketman updates the site every Saturday with a new page. You can check out the thread on blenderartists.org or go directly to the site. And dont forget to start reading from the first comic strip in the series!
