The instruments are giving solar scientists an unprecedented look at the sun, says Dean Pesnell, SDO project scientist. […]

Theoretically, the same set of blocks can be used to build tetrahedra and octahedra of any size. Thingiverse user Lenbok printed a set on a MakerBot.

Or sugar Voronoi cells, rather.
