I do have the building instructions. I sent the LDraw file, but it appears they didn't post that. I'll have to create the step-by-step images and submit those.
It would seem from some pictures I have to be bricklink part # 3482c02. But you need a lot of them... more than I have, at the moment.
Steve demonstrated this at NI Week, and it was fun to watch. I need to think up some "macros" for moving it with a more standard remote controler (to decouple the movement in the plane from the rotation of the platform). Watching the spectators react when the paddles "pushed back" was the best part.
There are certainly other ways to make such wheels as well, but Steve's is one of the simpliest I've seen, and works particularly well in this application.

I see some pictures but not instructions. I'm sure they exist...just not at that link (yet).

The vidio is awsome. I got to go build one of those.
Too bad Steve doesn't have a third hand ;o)
Cool remote. Is this the first NXT Killough's platform?

Steve, can you give the part number for the wheels? I was trying to find in the BrickLink catalog and I couldn't tell by the pictures
It would be great if lego made some holonomic wheels!

nxtgord, if you accept non-LEGO solutions the FXA308 Transwheel can easily be used on LEGO axles with a slightly shaved bush pushed in wheel hole.

Great.
Once the third hand is finished, you can make a fourth one by using the three hands. ;-)
M. (anxiously awaiting the building instructions (not for the hand ... well, would be nice to have them also))
The parts inventory on Steve's page showed that you need thirty-six (36) wheels to make it. Other than that though, it is not a very trying inventory.
Thanks Brian for the part number - I'm not sure how I missed it in the catalog. It looks like there are a few folks with more than 36 for sale.
I've ordered some of the FXA308 wheels, they're less than $4 each. Thanks for the recommendation Philo.
Well, I do have the advantage of a good picture and having seen it in person:
