Make Julia fractals using your phone and a mirror!

Interactive Video-Loop Julia

This tiny shader computes the complex square function. If you have a webcam, point it at your screen to make a video loop. If you point it off center, a translation is introduced, and we get a computation like this:

z -> z² + c

It's Mandelbrot's formula! You can see a Julia fractal!

I found this together with Trifox with whom I had the most curious time last night.
