Dark Matter

Dark Matter is a former factory in Berlin where they show light and interactive audiovisual exhibits in pitch-black rooms.  This year they have their first open sky light installation called Winterlights.

It's a 1000 m² (~10,800 ft²) area outside with 200 Christmas trees and 80.000 LEDs.  Lights, music, and smoke that repeats every 30 minutes.  It's pretty neat especially when there's a bit of icy rain in the mix.  

Although it is cold outside there's coffee and mulled wine to help keep you warm.

Here are a few videos I took.
