KD-Image City (WIP: Alternativa3D-powered) 

W-S-A-D to fly around with mouse drag look. Hold Shift to fly faster. 

Real-time processed image using Alternativa3D's KDContainer to generate a "growing/evolving" city layout.

This is still a WIP, intend to add optional road cuts per KD-Node/Building split,  flying/walking collision detection and other stuffs.
