Chess

 DaVici, 254 pieces. Interesting idea--a chessboard but a puzzle, with puzzle-like chess pieces. The puzzle itself is not very hard because of the relatively low piece count and the big differences in images, but it has one striking feature, which is that the images in the dark squares come from other DaVici puzzles, and the whimsies do too I believe. 3/5 certainly unusual
