Quoting Louis K.
Wow!. This ingenious, and probably the first one-colored mosaic ever. The shadow idea is just genial, even if it's a bit hard to identify the face. But I guess it's this ?
http://www.mocpages.com/moc.php/168062 All in all, I´m very impressed, great work, it must be so hard to place the pieces in the right order!
Thanks for the kind words. You're right - this is a small piece of the other mosaic. I'd actually planned on doing the whole thing but I ran out of corner panels. Why do I always seem to pick the most expensive pieces? :-)
