Domino mosaic art

Robert sez: "I've come up with a new way of making mosaics
out of dominoes. (An artist named Ken Knowlton
came up with another way in the 1980s.) Here's
what happens: You give me a picture. I then
take out 48 (or 49 or 100) complete sets of
dominoes and arrange them (using some software
I wrote) so that when we step back from the
dominoes, they look like the picture.

The site contains (virtual) 48-set domino portraits
of Abraham Lincoln, Albert Einstein, etc., and
photographs of a 16-set portrait of Marilyn
Monroe made of real dominoes."
