Anyone have any idea how this works? The images are very bright, and there don't seem to be any issues with the buildings casting shadows on themselves. If this is just a projector in front of the building, I've never seen a projector that powerful. And the effect will break down at any other viewing angle.

I would guess multiple projectors, an accurate 3d model of the building and skillful art direction. You project a video-textured model of the building over the real building. There were some other videos of similar installations floating around the web and they looked quite well even with somehow different viewing angles. For example, here are some with quite large camera pans: http://www.youtube.com/watch?v=X85A1dCpzsI http://www.youtube.com/watch?v=X85A1dCpzsI http://www.youtube.com/watch?v=3h3D6dCLAeo http://www.youtube.com/watch?v=3h3D6dCLAeo People are hardwired to see "3D" based on perspective / shadow hints in 2D images.

I've been curious about this as well, I found this post by a guy who gave a few details: http://crustea.vjfrance.com/article-21479794.html http://crustea.vjfrance.com/article-21479794.html Tech specs: Here are a few few technical details, the biggest mapping I've ever done so far. * 6 * 20 000 lumens projectors, to project on the 160m x 10m facade. * We'll use high res visuals: 1024x768 on each projector, so the output image is 6144x768. * To stream such High res format, we'll have 2 "killer" media servers, to run very large video files. * We'll use the VJ software Arkaos 3.6 to control the video, with multi output and Midi support, we'll be able to synchronize the visuals together and stream Gigabytes of video very smoothly. * VVVV will be used to sequence and root midi MIDI signals between computers. Edit: formatting
