This is the table that I sit my beer on when I solve puzzles. Crafted by Brian Young (alias Mr. Puzzle), the base was designed in 1995 by David Bruce and is called the Lost Day puzzle. If you disassembled the base and made one correct reassembly move per hour, it would take you a day to put it completely back together. Since I like beer when I solve puzzles, I have done no disassembly (yet). The corners of the base are eight different notchable six-piece burrs.
