What is the name of this thing
"What is the name of this thing" questions are off-topic. These are poor questions for the same reasons that "identify this obscure TV show, film or book by its characters or story" are bad questions: you can't Google them, they aren't practical in any way, they don't help anyone else, and allowing them opens the door for the asking of other types of marginal questions.
