And it just sits in a dusty glass fronted cabinet in a corridor. Minding it's own business as students go past to get to the great quad or down to the river behind. 35 years ago I used to wander by, going to and from work. It was one of the first webcams online in Australia too.

The old UQ electrical engineering building has a relic of another longterm experiment on its roof: a lighting observation booth, up on stilts above the building, with 360° views and a directional RF antenna for plotting strikes. Graham Rees, sometime deputy director of the computer center had been a student up there and said it was pretty bloody hairy when things went off. He also went to DEC Maynard and helped build the Dec-10 system which he brought back as the new campus multi-access system.

It’s an interesting and fun story, but what is the premise of the experiment?
