I find it pleasing to watch also. It is very decisive about its stepping. When
legs are moving individually, they do so realtively quickly, and then they all
move at once, you see a definite lurch in body location. There is something
about that that makes me just want to watch it walk.

If you have four pistons and four switches you can make a biped. In some ways
bipeds are hard because of the balance thing, but at least in LEGO pneumatics,
they are very simple (very much like a four piston reciprocating engine).

I'm really a neophyte when it comes to this stuff. Do you have other
suggestions on encoders I should use?
