       | Nice article. A lot of this looks very familiar from some
       | demoscene videos.

       | Definitely bookmarked the article.

       | I've been watching a playlist which is making shader programming
       | click for me:
       | https://www.youtube.com/watch?v=u5HAYVHsasc&list=PLGmrMu-Iwb...
       | "The Art of Code" channel, "ShaderToy Tutorials" playlist. I
       | think if you know some geometry/trigonometry, once you wrap your
       | head around writing a function that maps any pixel to a color
       | (and how you add or multiply colors, and think in vectors), it
       | starts to get fun. If you want a recommendation, I'd start with
       | videos 30 and 37 in the playlist for a cool demo, then the 1st 4
       | videos (note: the video quality improves in later videos), then
       | 10 and 11, then RayMarching starts in 22-24 and 29. (Many other
       | videos in that channel are great for shader programming
       | techniques, too.)

       | I had to look at that headline three times before it stopped
       | reading "Painting with Meth". Seemed a very non-HN topic!

       | For anyone interested in playing around with SDFs, my friend and
       | I made this open source library to make working with them more
       | efficient, and you can write shaders using javascript

         | Why would you write a shader using javascript and not the
         | dedicated shading language built into every web browser?
