The idea to use feedback loops to make walkers is a good one. I've made
a similar 6-legged walker using only three large cylinders and three
valves. This uses a triple-gait-cycle mechanism, meaning that one
cylinder moves the left legs back and forth, one cylinder moves the
right legs back and forth, and the last moves the centre legs up/down.
Of course, you need a three phase feedback loop in this case, unlike the
model you made, which has only two phases.

1: right legs
2: left legs
3: centre legs
Compare with a CyberMaster based hexapod for more description of how the
triple-gait-cycle works:

Unfortunately, this page is down right now, but hopefully it should be
up again in a few hours.

If it is an .avi, why does it have a .exe suffix? If it _was_ an .avi,
I could have played it on my Linux system, but the .exe I cannot use.
