Based on an interesting YouTube video I watched recently: https://www.youtube.com/watch?v=fDSIRXmnVvk

The 6-letter code in the upper right encodes a set of parametric equations, for x and y. If you iterate the equations many times (in this case 800) and draw the corresponding points, you get an interesting visualization. Change the “time” parameter, animate the result, and there you go.

You can also do things like configure the speed, color offset, click and drag to move, zoom in and out, change the time value etc.

Here are a few of the interesting codes I’ve found:

LYDMYF

VQCUDW

HLX_DQ

LBKITQ

EXCLNT

NMJNRV

The number of possible permutations of parameters is over 387,000,000 and no two are alike. See how many you can find.

(Note: may require a fairly modern device to run smoothly. If you’re on Mac, try it with Safari - WebGL seems faster than on Chromium)
