Hey everyone!
I hacked something together for this compo. It's a bunch of metaballs (and metafloor :) rendered with a halftone dithering technique (implemented as a pixel shader).
The full source code is included, released under the terms of the GNU GPLv3 (or later), see README and COPYING for details.
The code is cross-platform and should work everywhere, linux (32 & 64bit) and windows (32bit) binaries are included in the archives printblobs.tar.gz and printblobs-win32.zip respectively. Apart from the different binaries (and the fact that the windows package contains some dlls), both archives are identical (same source code).
