WebGL is fun, but still uncharted territory

My Russian friend sent this to me while I was working on creating ASCII art videos from mp4s.
This actually runs in a browser, making this image move.
It's a lot of fun. He also showed me the source code, and I really felt the strength of the Deno ecosystem.
And I muttered to myself, "Since there's no corresponding font in my environment, if I want to run it without dependencies, maybe I can import the font from CSS as a relative path, and then it would work in any environment without dependencies."
WebGL itself consumes a lot of resources, so I wonder how far it will be implemented in a practical range from now on...
