> Finding this particular spherical mapping took some time. There's no way to perfectly tile a square texture onto a sphere. It would've been possible to redefine the dither matrices in terms of a hexagon grid or something else that does tile on a sphere. Hexagon grids are flat and can't tile a sphere. Nothing can tile a sphere without knowing some specifics about the sphere, and even then you're pretty much limited to "orange slices", pole-to-pole longitudinal sweeps.
