Lovely and clear. A couple of interesting variations: 1) the small circle does one less rotation when rolling round the inside edge of the big one. One consequence is that when the two circles are equal then the "inside" one can't roll, it does 1 - 1 = 0 rotations. 2) You can also have a small square rolling round a big one .
