My Christmas Jigsaw Puzzle
According to Wikipedia, the first commercial jigsaw puzzles were marketed in England by John Spilsbury in 1760.
I haven't been putting them together for nearly that long. Every Christmas we buy a jigsaw puzzle and try to assemble it before the end of the holidays. Ms. Sandwalk usually gives up after the first day.
Do you know what "tessellation" means?
