Can you imagine it, a headset that that would let you walk down the streets of your city/town of 100 years ago. (or more or less)
Chose a virtual programme, say 1950, walk around your area, switch to 1960 then 1970. What a dream that would be.
Perhaps based on old photographs & video, the technology cannot be far away. I can't wait.
The downside: Getting kicked in the balls by some slack jawed youth in the present, when you are promenading along the banks of the Clyde, circa 1953. Small price to pay, I'd say.
Bring it on.
