We have decided to work on a game of joust featuring two horse-mounted knights. Each horse/knight combination is to be independently controlled by a cricket. Each cricket will have some idea of where it is relative to the other, but that's the only syncronization: the idea is for each cricket to determine (randomly) how fast the horse is going to gallop, and when to use the lance the bump the other knight off. This way, the outcome is always random and not known beforehand by any of the designers.
Each horse is mounted on a moving cart, and the four wheels of the chart are each connected to a leg, giving motion to them.
