Roll the odd shaped coaster, you think their movement is going to be random. Miracle! They follow these precise pre-determined paths. May be the world isn’t all that unpredictable after all. You just need to know the shape of your ride!
Can a shape fit into a set of identical shapes to form a plane – no overlaps, no gaps? That is floor tiles, I thought. That is Tessellation I am told. TESSELLATION.
Fit dinos into dinos. Play with tessellations of monkeys, horses. Or even make your own computer simulated tessellation.
