Designer Mike BaBoon has created a comprehensive periodic table of Muppet chracters.
Each square represents a different Muppet and the primary Muppeteer(s) for that character. It also denotes the year and production where character made its debut. Borders represent with hair or hat color, while the background aligns with the color of skin or fur, and color of the abbreviated name represents nose color (for the characters who have noses).
If you have been a fan of The Muppets throughout the years, you will definitely be able to identify these characters.
