If you are a game developer or are just starting, and don’t have graphics for your game or game tests, you can use Usklo.
Usklo is an art set for game developers including a race of little invaders from outer space and all their artifacts.
The latest released version includes one character with nine animations, props and one tile set. Usklo is made using free software only and it’s dedicated to the public domain. Its development will continue using gNewSense GNU/Linux.
