Thermochromic urinal. Way cooler than this one. And that one.

Update: I did not take or create this image. I found it on the internet, but I can’t remember where. There was no more details or anything like a source I could refer to back then, otherwise I would have. I get asked about it a lot and would love to find out more about it myself. If you happen to know this place, photo or the original source, please contact me, so I can give proper credit!
