I used to work for a company that made these kinds of almost art pieces. You definitely got a certain sort of client.

To be clear you can actually use them to cook food, they do work, but they are definitely more focused on the aesthetics side of things than the functionality. Having said that they do have things like timers and different cooking modes.

They come with instructions on how to clean them and it looks like a hell of a process so I don’t think I’d ever want to cook with them.
