I think I just died and went to puzzle heaven! This beauty you see here is a 1,000 piece jigsaw puzzle where each piece contains a unique color on the CMYK spectrum. The creator, Clemens Habicht—a true Renaissance man, working as a director, designer and illustrator—insists that because of the changes in color differentiating each piece it is actually much easier and more intuitive to put together than traditional illustrative puzzles. While that statement is yet to be seen, I wouldn't be surprised if it stands true for me, being a complete and total color nerd (I know, what a surprise!). Learn more about the puzzle, not to mention buy your own copy, at the very awesome Colossal Shop here.
p.s. This puzzle is a total analog version of this test, don't you think?
