Real temperature readings from US cities set the starting conditions on a grid, and you place insulators and conductors to steer heat flow toward a target temperature. It's Fourier's law made visible — heat always moves from hot to cold, and how fast depends entirely on what material sits between them.
An insulator slows the flow, a conductor speeds it up, and getting the target temperature right means reasoning about the whole grid's heat path at once, not just one tile.
