Haha, I didn't know feet could be used as a metaphor for spying. At the same time, many teams have posted their designs online, either on CD, youtube, or their team websites. You usually don't do that if you're so intent on keeping everything secret.
We used rubber hoses for 'fingers' on our intake on the Monday after kickoff; pneumatic tubing works just as well but we've found varying advantages/disadvantages to using either. But I do like that elevator, it seems that it would be better to use it as a shooter though
