    > spherical harmonics can have uses beyond lighting

    This math is also used in Ambisonic surround sound though newer techniques use planewave expansion.

    For games, the full-sphere encoding of Ambisonic B-format can be decoded for arbitrary speaker locations and the soundfield rotated around any axis. I'm not sure if its ever been used for a game though.

      ... also quantum mechanics. The textbook solution for the wavefunction of the hydrogen atom involves spherical harmonics.
