This is a twitter experiment enabling twitter users real time interaction with a physical art installation. The installation is a pyramid made from 5000 marbles, triggered by 5000 tweets. On its way to the pyramid each marble falls into a marble run filled with ramps, tunnels, pinwheels. You will see your marbles way through the rollercoaster live in the video streams below.
I think the thing might be jammed, because when I tested it out, I saw a little door opening but no ball came out. Wanna try it? Just tweet #marbleart.tv and watch the live feeds.
