                  Rich Piotter has an 8-motor / 4-leg walker (Spyder)
                  page here,
                  and another 8-motor / 4-leg walker (Quadrapod) page
                  here. 
                  
                  For a very advanced bit of inspiration, there's
                  an interesting page up about an 8-legged robotic
                  scorpion (24 motors!) project here. 
                  
                  Sebastiaan van Vliet has a lot of interesting
                  information up on his ongoing 8-motor / 4-legged
                  robot, Simone
