Lego GBC by Lawrie George
Lego GBC or Lego Great Ball Contraption is a form of Rube Goldberg machine where the aim is to move Lego sports balls from one machine to another.
The standard defines the rate of ball flow as well as the input and output bin sizes, and by having a standard it allows anyone to build a GBC module that they can then bring to collaborative displays.
