As I was scrolling through boing boing today, I came across a familiar face - the Periodic Table of the Elephants elephant, which hangs out here at the ACS building in Washington. Now, we've chronicled various periodic tables from beeriodic table t-shirts to a video periodic table to baked goods ones, but Mark Leach has taken the chronicling to a whole new level with the Internet Database of Periodic Tables. Take a gander at his extensive collection of periodic tables, great and small (including said elephant).
