Hi, author here. Thanks to everyone for checking this out. I'm sorry if some of the examples don't work across the board, most of these use WebGL extensions that might not be available everywhere. As some people mention in the comments here, and as mentioned in the introductionary text on the website, I've not been able to test this across a large variety of platforms and browsers and I expected there to be issues in particular on Windows using ANGLE. Please consider filing issues on github intead of/in addition to reporting them here so I can actually track them.
