What is it?

Spirograph-like effect created in canvas – click and drag around to draw.

The settings are fully customisable through a homemade GUI (which isn’t great) that allows user to change colours, line widths, background colour, speed of rotation and number of reflections amongst other things. Oh, and my personal favourite setting, RAINBOWFY.

Set the background to black, increase the strength and rainbowfy for a pretty trippy experience.

UPDATE - added a couple of more features, namely a colour indicator, reset and save options.
