Puzzle design is one of those realms that is the ultimate challenge on so many levels, and there are some incredibly gorgeous pieces that get made. Ironically i was recently talking to someone about how we haven’t seen any enticing new wood/metal puzzles lately, and then up pops a .org post by Benjamin with the 2006 entrants to the Nob Yoshigahara Puzzle Design Competition. And best/worst part is… you can read through pdfs of all the solutions to these mind bending puzzles as well (something about puzzle solutions is just as fascinating to me as sitting working on them ~ so i’ve included the gorgeous solution to the pencil puzzle below)
