I saw this exact setup on a CRT at a hippie festival in the middle of the desert. It was so cool seeing the mystery broken down in this video!

"It was called television." I have no idea what that is.

I've done many experiments myself 20 years ago. Man, the things that came out from This feedback art, are amazing. Almost like liquid plasma animations. It's actually creating frequencies and a sort of a phase modulation with video signals.

Fractals have always fascinated me, bot because of their appearance in math and nature and because of their simple yet complex imagery.
@stickguy9109
This guy really loves fractals
@AA_21861
Douglas Hofstadter has written about this in his book, called I Am A Strange Loop. Really fun to read, if you're into fractals.

Video feedback can get so weird. Like insane bubbling plastic neon, stuff much deeper than the initial images. My friend and I used to play with it using multiple CRT TVs and an 80s/90s VHS camera plugged into the main TV, then pointing it at another screen with static on it and then back to the looping screen, introducing new signal into the loop. It was mind blowing. I wish I remember exactly what we did but this was over a decade ago. I highly recommend checking out David Blair's YouTube channel. He built multiple iterations of an amazing mechanical HD video feedback device. It's extremely impressive and the only digital bits are the screens, cameras, and signal routers on the latest version. The rest is analog, no computation, but it's super meta visual feedback, using multiple reflected screens, feeding back into more than one camera, combining results etc. Words don't really explain it well.

Very similar to J. P. Crutchfield, "Space-Time Dynamics in Video Feedback". Physica 10D (1984) 229-245. (though I believe that used a more involved taxonomy for the various spaces of possible outcomes, however didn't get into multi-projector work). Neat stuff!
@ansonx10
I'm sure almost everyone has seen a camera pointed at its own output before (particularly if they aren't a zoomer), but it's interesting to realize that all it takes for that phenomenon to become a fractal is for a 2nd copy of the video feed to be displayed to the camera.

Sounds like a job for british youtuber extraordinaire techmoan.

Kudos for your ability to "think outside the box"... I can't imagine how many ((self included)) who must have seen the "involuntary fractal ScreenGrab-of-a-ScreenGrab effect". And yet you are the first one (only) that I have seen take this what in retrospect seems "obvious step", which imho is just another demonstration of your "creative mind". As always it was a pleasure to watch one of your interesting and thought provoking videos. Best regards

The MoMath museum has this and it's REALLY cool!!
@aleksandersabak
That was actually a whole intro chapter in a math book called "Fractals" I read in high school. It literally explained how a CRT TV and a live camera would create a feedback loop capable of creating interesting patterns. There would be an added effect caused by the scan lines of the TV and the camera not lining up, especially if the camera was rotated.
@AB-Prince
something similar, though not fractal like was howlround, where a camera was pointed at a CRT. it's the effects used in the earliest dr who shows' title sequence.
@deboisemeane
man why is your channel such a goldmine
@quantenkristall
Most fascinating part of your setup is using two or more virtual screens. In year 1994, I have been fooling around with positive feedback looping my 100 Hz 16:9 TV (analog, CRT , PAL, 576i - what heavy piece of about 32'' display) with the live view of my Hi8 video camera (with integrated analog recording/playing on/from a magnetic tape boxed in a truly small plastic cassette system - at least in comparison with silly, but most common VHS standard cassettes), interconnected by a S-Video cable (separate video or Y/C are synonyms). As expected, this generated kind of infinity mirror. When I started moving or turning the video camera I created wonderful spinning spirals, most of the white or blue colored - sometimes they started pulsing slowly or flashing fast. Truly fascinated, I spent for sure at least one hour craving for the most overwhelming effect. What a pity, I was not recording this pleasure of old school analog equipment. Feed back looping 4k digital video live stream from my DLSR on a 4k 27'' LCD display did not create the same amazing effects lately. Now, I very thank You for Your video clip here - it opens me the door of new perceptions of a much greater space of fantastic worlds to visit. quantenkristall aka FarbigeWelt alias Michael Trösch (born end of May 1973).

I did a lot of similar projects using Flash, back in the early '00s. One of the coolest effects I was able to produce was a rotating 3D cube that was texture-mapped with a distorted version of the screen itself, which gave similar effects as these fractals. Messing around with these types of fractals is so much fun because it doesn't take much CPU power and is completely real time. What I think is really funny is that pointing mics at speakers is painful, but pointing cameras at their own live video feeds is awesome. I guess the only time I can think of where audio feedback isn't terrible (in a live setting) is if you have an electric guitar near its own amp, and you can get some cool feedback effects that way.
