Hi all, I recently learnt how to write shaders with glsl, and I eventually began messing around with mandala-type equations, where each pixel's colour is changed depending on the distance and angle to the center of a texture. Some patterns emerged from what when zoomed in just looks like a regular spiral (see attached), but when zoomed out takes on some interesting forms. The pixel colours change according to the following: tan(distance*2 + angle) - cos(exp(distance/100))
Each colour is offset to produce the rainbow effect, with green offset by pi/3 and blue by pi/3 * 2.
Enjoy the eye candy

Very cool titus, thank you for sharing! The second last one reminds me of patterns I saw on some mushroom journeys

Thank you for these titus! I needed a new screensaver. I'd be interested to see what some of my artwork looks like when ran through this program.

These are good examples of what is called an aliasing effect. It's derived from limitations of the medium or of the calculations themselves, which can only have a certain maximum level of resolution whether in the digital display or in the number of significant figures in the numerical values. The patterns arose during the zooming process because the resolution became reduced.

That doesn't mean it won't bear some relation to some of the visual patterns seen in psychedelic experiences.

You can also see something similar to this if squinting at sunlight reflecting off surfaces, especially automobiles. I see it all the time sober.
