In the competition of browser games, Mozilla Labs Gaming won the game Marble Run ( github ). Each participant draws a track for a ball falling under the action of gravity. As the number of tracks increases, new construction figures become available. The people have already drawn about ten thousand tracks (see the gallery on the site).
The development used PrototypeJS , cookies-js-helper and box2d-js . Marble Run is a form of kinetic art; the route of the ball can be quite bizarre: it can bounce on springs, jump into new levels, move along inclined planes, etc. In any case, it moves along the programmed route. ')
In the best sculptures, the ball moves along the route for several minutes, and it can be difficult to look away from it.
The largest moving ball sculpture in the world is installed in the Hong Kong Science Museum and is 22 meters tall.
