Blender is an irc-based ansiscene competition where anything goes. Everyone goes onto irc and throws topic ideas in, and 3 words are chosen, then you have to make art from that. The words this year were WHALE, ASTROPHYSICIST, and CRATER LAKE.

My piece is a whale sitting on a Chinese lunar lander, which houses a space telescope inside, in one of the marias of the moon. I didn't win but it was fun to draw! I used a pixel art app called Pablodraw: http://picoe.ca/products/pablodraw/
