Pixen is an innovative bitmap graphics editor - by opensword
Pixen is an innovative graphics editor for the Mac. It's designed from top to bottom for pixel artists—people who make low-resolution raster art like the sprites you see in old video games. But it's great for artists of all arenas: Pixen is like a very powerful MSPaint or a simpler, more agile Photoshop. And best of all, it's Free! And the source code is ready for GNUstep.

The source package actually includes a GNUmakefile for GNUstep, but it seems it has not been updated for a very long time. The build fails immediatly, so there's no way to get the application working, sadly.
