I'm about 15 minutes away from releasing the Limnetic Fractal Explorer on Ko-fi for 5 euro 55 cent. There's a lot of stuff included in it, you can get properly lost in it. 3D fractal exploration with the option to add your own mathmatical equations into it, animated motion, extensive 2D fractal options, tons of lighting and colour choices a kaleidoscope lens mode that allows for some of that fuckery, it's pretty damn cool. Runs offline as html and exports huge PNGs/JPEGs/Tiffs. + More!
