I fiddled with lengths in Euklides till I got a reasonnably flat and horizontal
path for the foot, while keeping axle lengths even, and came up with this one.
After building I had again a closer look at this other simulation:
http://www.mechanisms101.com/theo_jansen.shtml, the bottom of the curve is much
flatter. This comes to a price: the descending part of the curve is almost
tangent to the ground, making it more prone to stumble. Probably the way to go
for low power design, such as the solar version discussed with Brian.

Yes, this system is really great... That said, if you go on the solar version
the old 71427 is much better regarding efficiency!
