Not everybody's into chemistry, but you have to be a special kind of insane to not have a fondness for the Muppets. This periodic table of Muppetry is a wonderfully organised and colourful take on the history of the form than anyone (with a soul) can appreciate, chem-geek or not.
Designed by Mike BaBoon, the chart is more than just Muppet abbreviations in squares; it actually gets some real information across. The background colour of each element/Muppet/muplement/elemupp represents its skin or fur, the border colour stands in for any hat or hair, and the colour of the abbreviation text matches its nose. On top of that, each box indicates the muppet's year of introduction, and the primary muppeteer. It's more data than you might expect, and all in a delightful form.
If this seems like something that belongs on your wall, you can find prints of various sizes for various prices at Redbubble and Society6. And study up; there will be a quiz. [Mike BaBoon Design via Buzzfeed]
