At Claremont McKenna college, chemistry professor Babak Sanii and his students have created an online tool that allows users to create "Elemental Cardograms" — periodic tables where the area of each element is made larger or smaller to reflect the chemical composition of specific items, ranging from tattoo ink to corn.

Other fun projects: How many (real) elements are mentioned in Star Trek episodes and how frequently chemical elements are referenced in song lyrics.
