what technology and/or company's product was it?

I used to do some VR work back in th eearly days...

It was the Industrial Virtual Reality Expo in Tokyo. About 100 companies demoing all their stuff. The headsets we liked were from Crescent.

this the huge thing that was shown a year or so ago?

Yeah, though they also had a bunch of smaller units. Some force feedback stuff, multi-touch floating displays.

It's more the venue and the interested parties. Should have seen all the auto company execs drooling over this stuff.
