So I ran across this: http://webdev.stephband.info/parallax.html

And a couple of the demos looked like they could get used with mapping....

Image a city map with mupltiple building levels: http://webdev.stephband.info/parallax_demos.html

Imagine a space sector map with system layers framed inside this grid: http://webdev.stephband.info/parallax_demos_target.html

All iot needs are transparent images...
