Slouching playdoh container

I've spent way too long trying to make a two-legged walker with a second servo I liberated from the TUI cafe, and that's really difficult!  So instead, here's my backup, a much lamer play-doh container sloucher -- not really a walker or a crawler.  It's the code from the lab, controlling the servo with the potentiometer back and forth.  The lid is attached to the servo and slightly unbalanced, making back and forth motion translate to side-to-side and slightly forward motion.  The cup stabilizes the apparatus.
