Tenori-On prototype spotted in 1997

John Carpenter, film-maker and electronic musician, predicted the Yamaha Tenori-On back in 1981. In his film, Escape from New York, which was shot in 1981 and set in the bleak future of 1997, he predicted that by 1997 all government agencies would have their own Tenori-on visual sequencer. It still needed a little more work to fit all the electronics into a more manageable hand-held device, but it was mostly there.

He also showed the prototype handheld Tenori-On-Red, but it was scrapped as it had too few lights.

It even came with a vectored flight sim as an easter egg.
