M.C. Escher Automoton Avatar *boxed*

From my experience:
1. You may be disappointed with how or how not the elbows line up, depending on how or how much the arms bend.
2. The neck has the potential to line up oddly with the torso, while moving, depending on the Animation Override.
3. You or others may see the joints of the avatar misshapen / get smaller, as the distance from the avatar increases, depending on the viewer settings.

This is currently my main avatar. It's nondescript but interesting and uncommon without being outlandish. I like it a lot.
