That's a nicer approach than mine and, with a minor change, works for
arbitrary (clipped)0 tiling as the result can be interpreted as
indices:

   ]k=: ?.3 3$100
94 56  8
 6 85 48
66 96 76
   (,k){~8$8$"1 i.$k
94 56  8 94 56  8 94 56
 6 85 48  6 85 48  6 85
66 96 76 66 96 76 66 96
94 56  8 94 56  8 94 56
 6 85 48  6 85 48  6 85
66 96 76 66 96 76 66 96
94 56  8 94 56  8 94 56
 6 85 48  6 85 48  6 85

Thanks,
