Can someone give more context here? It's a cool 3D map, but this submission is at almost 100 points and I have no idea what it's about. Is this submission about...

- A private or open-source map visualization engine that's doing something new? (And if so, what?)

- A demonstration of all the 3D data already in OpenSourceMap? (Has it made a leap forwards or something? How complete is it?)

- Something else?

Is this something new and newsworthy or just somebody re-posting something that's been around for a decade? I'm just totally lost here.
