At the entrance of the futuregarden a beamer, a laptop running my processing script (here at github), an arduino uno and a hall sensor were hooked up. The beamer pointing at the canvas projected five additional colors to create five new colors.
Each time the door of the futuregarden was opened and somebody entered or left., five new colors were thrown on the canvas. These five-color palettes were created using the “crowd-color” platform colorlovers. In addtion, to my own color palettes, I featured some others I liked:
The result was the perfect atmosphere to enjoy a beer.
