One of the co-founders of Wolfram Research, Theo Gray, owns a home made, wooden periodic table table with compartments underneath every element label, with samples, if you’re a chem geek you’ll have probably seen it before. Gray built and populated the wooden PT in his free time. Kirk Zamieroski of the American Chemical Society tells me Gray also has “a ridiculously bizarre element collection.” You get to see some of it in this expo of Gray’s PT and collection put together by Zamieroski.
