I watched a show today, the Secret Life of Chaos by Jim Al-Khalili. An interesting point is that he redid Hofstadter's demonstration concerning pointing a camera at a screen which is displaying the camera's output producing video feedback. I expected a nod to be given to Hofstadter, but there wasn't.

Pretty sure that he's real.

Hofstadter was not the first guy to do that. Many, many people have set

up such feedback loops. I remember tripping out on the recursive
reflections in the mirrors at Sears. That was long before I read
Hofstadter for the first time.

OK - well, to heck with any sort of credit to Hofstadter then.

Also, the mirror recursion is quite a bit different than video feedback.

In that no electrons are being disturbed ??

In that the mirror deal is just pure optical. Each repetition diminishes because you lose photons each time. You can't get a perfect recursion because your head blocks the view. You can get a perfect recursion wih a camera and that's when you get all the weird patterns as seen in Hof's books.
