POPSA New Free Encyclopedia for Developers Another interesting aspect of this encyclopedia is that you have the possibility to download and publish and even redistribute it.

POPSGenetica: The best free texture tool on the net Spiral Graphics is doing amazing things. Along with the free Genetica Viewer, I strongly recommend their Wood Workshop (also free) and the huge texture packs. If you don't want to download and install these tools, there's one more chance: their web site has a built-in Genetica plugin so you can browse, render and download the textures you selected. Excellent resource.
