I have some silly ideas for Memix shaders, if I get the chance to implement them I will post them here.
Download Memix from https://www.memix.app/
Copy a shader source to %LOCALAPPDATA%\Beautypi\Memix\shader.txt
This should replace the "Custom" shader in memix.
Note, some of these shaders are slow. Use at your own risk, sorry if your GPU catches fire.
