Memories! I actually scanned the video several times to see if I was in the background on the stairs. I remember seeing this being put though the paces in this space (those were CS offices in the background, I don't think this drive-through exists anymore.) Not sure that I saw Ivan driving the hexapod though.<p>There should be a Robotics Institute technical report about it, I recall Claude Shannon wrote a whimsical poem about the the hexapod.<p>[edit] some context: Ivan was a founder of Evans & Sutherland, a groundbreaking developer of computer graphics systems. From the wikipedia page: "Most of the employees were active or former students, and included Jim Clark, who started Silicon Graphics, Ed Catmull, co-founder of Pixar, John Warnock of Adobe, and Scott P. Hunter of Oracle."<p><a href="https://en.wikipedia.org/wiki/Evans_%26_Sutherland" rel="nofollow">https://en.wikipedia.org/wiki/Evans_%26_Sutherland</a><p>He is also known for Sketchpad, perhaps the first graphical user interface:<p><a href="https://en.wikipedia.org/wiki/Sketchpad" rel="nofollow">https://en.wikipedia.org/wiki/Sketchpad</a>
