From Doug McCune's blog, the motto of which is: "I was Web 2.0 before your grandma was Web 2.0" which is kinda cute, gotta admit. Not that my grandma was ever anything close to that, she was a great baker though.
Anyway - he says: "I’ve been playing with different ways of representing data and I decided to venture into 3D representations. I’ve used a full year of crime data for San Francisco from 2009 to create these maps. The full dataset can be download from the city’s DataSF website." These are really rad and interesting.
He's chosen a solar illumination from the east, as it would be during sunrise.
He has a disclaimer: "These maps were generated from real data, but please don’t take them as being accurate. The data was aggregated geographically and artistically rendered. This is meant more as an art piece than an informative visualization." which is valid, but these are still really nice.
