Here's a New Year flashback to 2003. The Thermochromic Toilet seat is an acrylic loo-saddle containing heat sensitive ink. The ink changes color at 36ºC (97ºF) in order to let public toilet users see which seat is still warm.
Designer Peter Crnokrak:
This could also have been useful in English Public Schools, where the now discontinued practice of Fagging required the younger boys to warm the seats of the seniors. These days it would just the thing to avoid what Douglas Adams called Shoeburyness (The vague uncomfortable feeling you get when sitting on a seat which is still warm from somebody else's bottom).
