I've been obsessively playing with jigsaw puzzles of photographs on
National Geographic.com. Each one only takes 4 to 6 minutes (for me) to complete, on average, and the photographs are truly beautiful. Hundreds or thousands (I can't be bothered to figure out an actual number.. :P) to choose from, by catagory. I'm rather partial to the photographs of sunsets, flowers, and cityscapes. ^_^*
I can't stop!
(I really love puzzles... and mysteries.)
