At the SIGGRAPH '96, where they launched the N64, SGI had an awesome stage show: there was an MC and a user with a VR setup on, some Onyx refrigerators behind them, and a big screen showing the VR view.

It was awesome - they were basically building New Orleans with legos: open a toolbox filing cabinet, choose a brick, run it all the way down the block, run that line of bricks up 200 feet to create the side of a building, rinse repeat.

Would love to see that one again.
