Science + The Muppets = Awesome
Artist and designer Mike Boon created this fantastic Periodic Table of The Muppets in which each square represents a different muppet character and also indicates the primary Muppeteer(s) for that character along with the year and production in which that character was debuted. But that’s not all:
"Borders align with hair/hat colour, background aligns with skin/fur colour, and colour of the abbreviated name represents nose colour (for characters with noses that is)."
