Title: Infinite Loop Web Cast at ever smaller scales Post by: Nahee_Enterprises on April 12, 2010, 02:11:38 AM Someone was doing a live web cast, using a camera, a computer, and the application running live at the time. They decided to see what happens when one points the camera at the monitor during the live web cast:

It's like twisting around inside a tunnel...
I'm interested in the pulsing "tones" that it started producing. I suppose these were the only attractor under iteration of the feedback loop. If their network speeds were varying widely, I wonder if they could have observed some types of hysteresis... :yes: Title: Re: Infinite Loop Web Cast at ever smaller scales Post by: cKleinhuis on April 12, 2010, 08:25:53 AM in fact you can generate julia shapes with moving the camera around and recording what you are outputting ;)

http://www.youtube.com/watch?v=uzzktnjKkVg In your case up there, it was audio feedback aswell... That's more rare. I guess, it's because that gets a mess quickly and doesn't sound as pleasing as video feedback looks.

I discovered some interesting effects myself, using various processing features of the webcam i have, but i haven't gotten around to putting any of it up yet. Maybe you'll see something soon.
Title: Re: Infinite Loop Web Cast at ever smaller scales Post by: Calcyman on September 05, 2010, 07:43:02 PM You only get a fractal with two or more screens. Otherwise, you merely have a recursive image with a single pathological point.
Specifically, each screen corresponds to a projective transformation (not necessarily affine), and the result is a system similar to Barnsley's IFS fractals. You could, for example, create a fern with four screens strategically positioned.
