Apple uses quintic superellipses. Very similar to squircles but not quite.

  What does quintic mean in this context? My first thought would be something like (x/a)^5 + (y/b)^5 = 1, but that doesn't seem to work. I only get meaningful shapes when I use even exponents.

      Ah that makes sense, thanks. Obvious, in hindsight.
