Since we’re talking about puzzles and games, I thought it was worth pointing out Lee Krasnow. Lee is a puzzle-maker from San Francisco, and creates some awesomely perplexing objects! There is a great interview with him over at makezine, in which he talks the viewer through some of his puzzles and introduces us to his method of working.

Perhaps the most incredible thing is that Lee's tool of choice is a table-saw. Using a jig of his own design, he manages to cut highly precise and tiny parts – he has posted an instructable describing how to make some jigs and ten of his puzzles here. It’s daunting, but highly inspiring stuff and makes me think that there’s no reason why a laser-cut puzzle should be just a 2D affair.
In fact my favourite Ponoko project of late has been Carbon by ckharnett (a recent product of the week) – a game-like geometric construction of simply hexagons, pentagons and triangular connectors. The constructions possible with this system are endless!
