This idea involves two quite separate bits of technology to achieve aesthetically similar aims.
I've just been gazing at a log fire.
There's something very evocative about the bright hollows in and under the burning logs. They remind me of the childish delight in small spaces to explore, with
a premium on really complicated, mazy topography.
I'd like a heat-resistant sensor that I could push into the embers, which would capture those shapes being hollowed out of the wood, and the brightness of them, and feed this information into an editable virtual reality representation. The possibilities of the spaces themselves might be rather limited, but they could serve as a wonderful backdrop for a first-person game of some sort.
That's the 'hell' part. Not really evil, I admit, but it makes a nice contrast with the other part...
There's one other sight in nature which does the same sort of thing for the child in me, and that's the kind of cloud formation which, in certain lights, strongly suggests landforms, with beaches, cliffs, plateaux and hills.
So, we need another, probably much more expensive system, for capturing these shapes and colours. I suppose we could get some of the data from a series of photographs from the ground, but that's not really ambitious enough for the half-bakery; we'd want to supplement it with a scan from a passing airborne platform (maybe a hullaballoon).
Then, do the same kind of VR-ing as for the fire data... then put on the VR goggles (or whatever other kit is available) and climb those cliffs, stretch out on the edge of the vast lemon-and-rose-petal plateau, and look down...
I suppose Google Earth might one day stretch to Google Clouds, with this sort of effect achievable.
