L'Assemblée Nationale is the equivalent in France of the Congress.
For the opening of the COP21 conference in Paris, the front of the building has been light-painted with a video showing a crowd of people.
The people are first seen from behind then are slowly turning to face the camera. A very nice effect!
Ten huge video-projectors were used.
I've put in the inset the pictures of the artists responsible for this display.
Right is the french artist-photograph JR and left is the renown american director Darren Aronofsky.

My dual rig attracted some attention and I started to discuss with the crew and showing them some of my stereo images.
I didn't realize first that I was showing my pictures to the director of Black Swan, The Wrestler and Noah!
BTW Noah was screened in 3D in France but I don't know if the director was involved with the conversion.
