You always wanted to play with those motion capture files that you can find for free by the thousands on places like the Advanced Computing Center for the Arts and Design or the cgspeed site which contains BVH conversions of the 2500-motion Carnegie-Mellon motion capture dataset.
Well, now you can.
I have written an importer package for the BVH (Biovision hierarchical data) motion capture format, which you can find as an answer on mathematica.stackoverflow.com. Just three of the possibilities:
out = Import[ "C:\\Female1_D6_CartWheel.bvh"]
GraphicsComplex[#1, Line /@ out["Bones"]]} &,
Boxed -> False
Combined with all the graphical power of Mathematica the possibilities for fun projects are endless. How about this?
