45'x12' projection wall powered by a Vista Spyder splitting the image to 4 projectors. The visuals are from a Processing application featuring 1500 blades of grass which blow in a perlin noise flow field breeze. The blades of grass also ripple and bend when people walk by because of an infrared fisheye camera mounted in the truss to pick up motion. 40 fps for the final. The two kiosks in front of the screen allow people to enter messages that appear on the projection wall. Maybe the next version can accomodate text messages from phones.
