I’ve been using Blender3D for about two years now. Here’s a little Christmas animation I whipped up.

That’s supposed to be sparkly glowy things coming from his shiny nose, but it looks more like a puff of breath. I’m pleased with the head motions. I’ve got the eyes rigged up so they can blink and track an object, and I’ve got the two front legs rigged. I’ll probably try to rig the other legs and do a simple walking animation, but I’m through for the day.
