The world's potentially largest public toilet door art piece with HTML5 and node.js

The Eternal Toilet Door is the world’s potentially largest public toilet door art piece.

Everybody can paint the toilet door in realtime and can see what others are painting. The door grows to the top till infinity and the picture is saved as many small images. You can also use an iPad and probably other tablets to paint because everything is HTML and javascript. Additionally I sampled real toilet and painting sounds to make the experience as real as possible, so consider it also the first toilet door painting simulation ;) Technically I used Backbone.js, Coffeescript, node.js and socket.io. Feel free to paint something, if you do not know what, here are some ideas for you: “I am Batman”, “Mom” with a heart, “Randy wuz here” and so on.
