This character is inspired by Etienne Decroux's "Mime Corporeal" (https://en.wikipedia.org/wiki/Corporeal_mime). I used and still use it for my work with motion capture.
The armature of the character is constraint to a bvh skeleton, which makes it easier to connect the character to bvh data (well not that easy, as you cant import bvh files directly on an existing armature ;-).
Anyway, enjoy!
Nice model, Thanks for sharing ;p
