Could not find any way to contact you.
I'm gonna add your glpaper package to nixos rep.
And have a question: is there a way to support mpd's fourier output and to channel it to shaders using your program? Would'be cool. I know some C ( at 42 ecole we did some part of libc and some other projects ), i could help with that ( and port some shaders that use audio channel from Shadertoy for example )/
EDIT: Oh, and it conflists with sway-bg ( it wont draw if bg used ) - could there be a workaround? With regards, D.
