i write a lot of shaders, particularly shader toy shaders. small, single-file fragment
shaders that draw something cool. using math obviously.
my more "serious" shaders are available shadertoy.com. that's where i started
in fact! and as i'm typing in their in-browser text editor, typing lines of code, and immediately recieving
visual proof of the expression that i *just* typed, sometimes i'll ctrl+C, ctrl+V into a folder on my
desktop. that's what this is. or, that's what the gallery is!
