How does it cope with uneven ground? It would be interesting to see a
vid of it pulling itself over rough and bumpy terrain.

Ah - some kind of chicken walker. The thing that interests me most
about pneumatic walkers is that they are compliant, and their method
of movement may allow them to deal with difficult terrain in a
different way from a servo controlled walker. At some point I would
like to try to put together a walker with forward/reverse as well as
left/right control from a controller playing rider to a pneumatic
walking system that handles most of the walking motion.

Probably I would say Xvid - it is free, legal and fairly simple - it
should present itself as yet another codec when playing back or when
encoding. The windows binaries are available at http://www.koepi.org/
