I made this neon animated hexagonal effect thing for the UdeMHacks website. I got the
initial design from this CodePen , but I rewrote it in TypeScript and added some
extra features. I tried really hard to make it run only in a fragment shader instead of a 2d canvas, but I couldn’t
get it to work. The original pen had a black background and just fills the screen with low opacity black to have the
fading effect, but to make it have a transparent background, I had to do some globalCompositeOperation shenanigans
and some GLSL magic. Just doing globalCompositeOperation doesn’t fully work because leftover pixels from the
previous frame will still be there. I use the shader to not render any pixels that are too transparent.
