I remember trying a VR game in a shopping centre in Malta of all places in the 90s. They strapped you in a harness and you walked on an omnidirectional treadmill within a "ring".

The game was basic, early "3d" (in the gaming sense), low polygon, low resolution, no depth or actual streoscopic, but this was the 90s.

I tried to check it out again on a subsequent visit to Malta but it had of course gone. Real shame, I saw nothing of its kind for decades later.
