    Does anyone know of a way to partition the Celestial Sphere using the grid of a truncated icosahedron (the geometric pattern of a soccer ball)? It would be an interesting way to divide the night sky into 32 regions of nearly equal size (20 hexagons, 12 pentagons).

    Ideally, the grid would be adjustable (click and drag) to experiment with orientations that preserve the constellations, in the same way this world map example preserves continental regions: http://s1.hubimg.com/u/2230748_f496.jpg

    Is it possible to add such a feature to Stellarium?

      Apart from being an interesting curiosity, I don't see what purpose this serves,
      and I strongly suspect it's non trivial to implement.

      You might find your exploration can be done via mathmap, a
      Gimp plugin, that (amongst other things) was used
      for initial reaearch into the "Pannini" projection for wide angle panoramas
      back in 2008.
