ha, great minds. Posted nearly the exact same thing, but you were first, so upvote for you.

This is beautiful. Have you looked at Stephen Wolfram's Physics project?

Reminds me of watching his idea of spacetime coming into existence.

Love this, thank you for sharing.

Take my money.

Excellent work on this. You can feel the craft and time you put into this post. Well done.

Don't forget Prototype (http://prototypejs.org/)

and scriptaculous!

YUI https://clarle.github.io/yui3/

Do we need to get into underscore etc?

Heh, yeah, I was a heavy Prototype user back when it wasn’t clear which one of jQuery, Prototype, Scriptaculous, dojo, or mootools would ‘win’.

And Dojo! https://dojotoolkit.org/

Oh man, back in the day I got my first exposure to big, enterprise web apps in the form of an undergrad internship on a control panel for a major database that ran on Dojo. Every time I could scurry back to Python to work on a backend feature, I breathed a sigh of relief. It put me off frontend for a long time until I arrived at a shop that taught better, and not being taught was definitely a big part of my fear of Dojo/frontend dev, but Dojo is also BIG and you can build some really unwieldy systems with it. You can do that with any framework, sure, but in the heyday of Dojo, it was a lot of opaque logic that wasn't as well doc'd out or understandable just by reading as today.

Dojo put the fear (respectful) and fear (scared) of big, enterprise frontend development in me.

This is really cool. Thanks for building it.

Not knowing how to do it and reading and failing until I figured it out. Repeat for 15 years to become a skilled crafts person.

I shared a desk with Andrej when he was interning at our lab for the summer at the University of Toronto. One of the smartest people I ever connected with about all CS topics. Hopefully he finds what he is looking for and takes a well earned break.

I love computer science.
