Yes, you are correct. That was Carter's collection.
As for additional footage... no, only what's shown on that clip. I did play with each puzzle a little bit. They all turned very smoothly from what I remember. The one that is shown twisting at about 1:17 into the video was difficult to line up properly, but had excellent turning.
in oyour video of random cubing, you show some footage of a couple custom puzles, i belive they were a megaminx icosahedron, cater's triacontahedron, and a dodecahedron 2x2x2??? Anyway, you wouldn't by chance have any footage of those puzzles in action, would you?? because im really interested in seeing those as well as any others being used.
