A pair of wooden frames can hold a collection of hexagonal objects. When shaken, the objects gradually form into a hexagonal grid, conforming the the container.
One of the frames has a few additional hexagons fixed to the base; try comparing the time/work required to form a lattice with or without these seeding points.
