I've been thoroughly enjoying the 10 Cubes Challenge on Blender Artists so far: the severe limitations on your model means I can create something in under 30 minutes, and the prompts give me the nudge I need to get started on something.
Sterling posted the new prompt, Villains today. What will that mean for you?
As always, you can find the rules, prompts and entries in the 10 Cubes category on Blender Artists.
Have fun!
