#spheres

A ball made from a flat grid: one direction of the grid becomes longitude, once round, and the other latitude, from pole to pole. The grid's two side edges meet in a seam along one meridian, and its top and bottom rows each shrink to a single point, the poles. Anything read from the grid's place jumps at the seam, so a shader reads noise and colour from the point on the ball instead.
