[Penrose is suing toilet-roll manufacturers for using his non-periodic
tiling pattern]

Apparently `quilted' toilet paper is popular, but regular quilting
patterns tend to give unsightly bulges on the roll.  Aperiodic
patterns, on the other hand, don't have the regular repeats and so
don't suffer from the bunching.  Still, perhaps they should have asked
first.

  Cut-out-and-colour-in penrose tiles (toilet paper is a bit flimsy, I
