I'm working on the creatures you can encounter in Gnoblins at the moment. Currently there are almost 20 different creatures in the pipeline, most are still in the modelling state. But I've created lot of new blender templates for rigging certain types of models (like humanoid, quadruped etc.), a new texturing template and new tempaltes for baking and rendering models. The current pipeline is modeling->rigging->texturing->animation, all done in blender, even the complete texturing process. Here's a render of a golem I've almost finished so far.
The golem demonstrated the art guide we have developed over the time. The golem is one of the creatures I've created alone from concept over modelling and rigging to textureing, so by definition it is programmer art ;-) Nevertheless, I believe that it is a decent improvement over a simple ascii text in your common roguelike game ;-)
