@rejon pointed out that 20 year and older patents are fully public domain (images on newer ones are potentially public domain, as long as you don't use it as a way to sell how to make the product under patent and just use it as an image) so I decided to find some fun patent images. I found out that magician Penn Jillette held a 1999 patent for the "Jill-Jet" which was a hot-tub jet especially angled for a woman's physical pleasure. From light research he seems to have installed one at his house, but never really ended up selling them on the mass market. Fascinating what people think up.
