Some of you may have already seen this one, it's making the rounds on the net. It's a wooden periodic table of the elements.

The construction history on this thing is pretty interesting. Here's a quote:
As an aside, a brief note on woodworker chauvinism. There are two ends of the spectrum available for the woodworker wishing to have an attitude. At the one end is what I refer to as the Zen tool collector. This person is likely to tell you about their new hand-ground Japanese pull saw with teeth personally filed by the master saw maker Ibechi Yamatuthi himself. Their shop will sport the finest in electronic dust collection equipment, and everything about it will be spotless. Including the dust filter, because they've never actually built anything.
At the other end of the spectrum is the guy who spits on the floor and says "Hell, I could make a better table than that using nothing but a broken beer bottle and an old tire iron. And an electric drill. [Snort]". This is the sort of craftsman who believes that skill and long experience are what matter, not fancy tools from a catalog that looks more like the Sharper Image than a hardware store.
