A closeup of the walker feet in action is available via this video:

Go a few minutes before that and you'll see the entire design process, including each of Team Hammond's iterations on the design. Also, a great sneak peek of the 2002 Zone Zeal Kickoff broadcast is available starting here, with bonus footage of Team Hammond's strategic process:

(Yes, that is a VHS player. 2002 is longer ago than it feels, sometimes.)
Bonuses in this video: young Dave Verbrugge, announcer Ron Partridge, Woodie MCing matches, and Team 71's 2002 Chairman's Video (they were a bit different back then).
But most relevant to this thread, the inimitable and incredible Woodie Flowers Award winner, Mr. Bill, once again predicts the future: https://youtu.be/CuFlA3Pt4HQ?t=2014
