For reference:
Sleepyhollow is a fictional town where "the headless horseman" story took place. The horseman had lost his head in the revolutionary war and now terrorizes the town looking for his lost head. Modern media often depicts the horseman as having a pumpkin replacement head.
Code:
I compressed array V into a character array, saving about 581 chars
Added treadmill, colors, hands, feet, and a pumpkin head.
todo: The treadmill runs a little too fast.
