I decided to make a small octopod using small pistons.
It uses two small pistons per switch, chained together as a 3 segment inchworm.
Small pistons act much more quickly than mediums, and Bovinius tends to kick its
hind legs out like a bucking bronco (bovinius => bovine => cow). For those who
say I never add decoration to my creations (Are you listnening Eric?), I added
horns to complement the bucking action.
