Kitchen Floor puzzle from William Waite, 1998. I don't appear to have an instruction sheet for it. "William Waite" is laser-engraved on the inside of the tray. One of his many, many laser-cut tray puzzles. You're supposed to make a symmetric design with the holes; there are some notes about this on William's website. Despite there being LOTS of solutions, it's pretty difficult to assemble. I was happy to assemble it without symmetric holes. Puzzle weighs under 3 ounces.

This is a 1987 prototype of an unusual three-dimensional puzzle and/or game in which blocks have to be assembled in such a way that the black areas continue from one block to the next. It comes with a photocopy of typed rules -- but they are in Italian only, so I do not know how the game/puzzle plays exactly; there are 4 pages of illustrations plus 6 Polaroid pictures of the blocks assembled in various ways; from these photos, it appears that there are design elements to the game.Bill's Game was...
