JSimbicon
Meet bip7, a 9 DOF physically simulated planar biped!
You can push him around with the arrow keys. Bip7 knows how to walk (press 'w', default controller), run ('r') and crouch walk ('c').
He has many other skills but not in this demo version (at least not yet).
Also, press '1' to make the ground flat (default) or '2' for a more challenging course.
