Amazing "proof of concept" video for multi-layered view

This video is actually a bit old...and I may or may not have posted about it awhile back. But no matter! It's cool enough to share again, and hopefully some of you haven't seen it yet

Dwarf Fortress is 3D...but only just barely. Better said, it has a bunch of 2D planes layered on top of each other, sort of like a cake, with very little visual relationship between each of the layers.

The below video suggests a slightly different way of handling this view. It keeps the layered approach, but it instead makes each level opaque, so you can easily visualize the 3D nature of the game world.
