As described in Douglas Hofstadter’s book ‘Godel, Escher, Bach’, this is what happens when you connect your camera to your TV and point the camera at the screen. The spirals are created by tilting the camera.

I’m currently reading this article here which links to the video. The article is about a zip file that contains itself.

    I used to entertain my kid with this. Have them stand between the camera and the display and they can amuse themselves for a (relatively) long time.

    I first learned of this watching sightings in the 90s. Oef course, the show said you would see faces of the dead going frame by frame, but that doesn’t make any sense

      This reminds me of a fascinating bit of information that keeps swirling around in my head ever since I listened to that radio show in the 90s. It was about people who listen to messages in radio static, until they believe they hear something there. Of course they record it all, then play back and loop the relevant bits. Listening to it, you think you can hear these messages too. Having been told what they are beforehand, of course.

      A little bit like a much later trend of putting fake english subtitles on songs in foreign languages that make it seem like they’re singing extremely silly things in english.

            Ah. I forget Lemmy has a wider international range. To be fair, some American AM stations were known to bounce all over the world.

              I forget Lemmy has a wider international range.

              Thanks for acknowledging that. Too often I feel I have to justify myself for - well, anything that puts me apart from US Americans.

              Are you sure you don’t mean shortwave? According to this article the furthest for AM is ~1000 miles. That’s 1/5th of the way to Europe.

    The delay is considerable. i think this would look different with current technology.

    Is there some sound feedback, too? A very high beep, not constantly? Or is my tinnitus playing tricks on me?

      If anything, modern tech introduced much, much more delay. Digital encoding and decoding takes time - and so do packet based transmission protocols.

      Back in the day, radio moderators monitored their show by simply having the radio station on their headphones. That was over the day digital workflows were introduced.

      IIRC typical online live video streaming today typically has a delay of at least 2-3 seconds, to avoid jitter and stuttering.
