APL seems like a great language for computer graphics! Has anyone tried their hands at the same?

The author also has this video: https://dyalog.tv/APLSeeds21/?v=iC9floP7POU "Tomas takes you through the API of a 3D-engine and shows you how to connect to it from APL, enabling you to create a simple scene with graphics objects moving in real-time. He also explores some of the more advanced rendering techniques." (I haven't watched it)

Very cool, this approach will inevitably catch on, I think. I built a similar typed PL and compiler for Morgan Stanley back in 2013: https://github.com/morganstanley/hobbes
I read about Hobbes years ago. The embeddability certainly caught my attention. I wrote Empirical specifically for the use case of wanting to read a CSV file while inferring the type at compile time. Basically, a ton of compile-time function evaluation mixed with type providers.
Well this is unexpected - didn't think my little study group would appear on HN! :O Well anyhoo, all are welcome to join; details in the linked thread (including playlist of last week's videos so you can catch up). As it happens, my interview on The Array Cast was just published today: https://www.arraycast.com/episodes/episode31-jeremy-howard In it I discuss my thoughts on array programming, including in PyTorch, nu…

And J is almost isomorphic to APL.
I recently did a project using Dyalog APL. I really wanted to love it. On the pro side, the community was great and I loved the language, but only to a point. There are way too many instances of utter astonishment at behaviors that seemed to be just how the language works. I had a lot of trouble finding good, mature libraries for things I’ve taken for granted in other languages. I’ve found that Julia provides 98% of…
He got me to teach him basic C syntax and then took off on his own, writing a game. After a few weeks of hacking, he presented me with a decent Asteroids clone, "I don't see the point of C."
The funny thing is, when I looked at his main.c file, the entire code was written inside the main function, with copious use of gotos. He had essentially tried to speak BASIC using C.
APL isn't an Algol-like, and you're probably going to have a bad time writing APL trying to use the cognitive tools and intuitions you have as a programmer of Algol-like or even functional languages. This includes the tendency to reach for libraries, when you can, for example, implement an entire U-Net CNN in 30 lines of APL and be competitive with PyTorch performance.
In my (budding) experience, to "get" APL you have to laser-focus on writing beautiful, concise code from the onset. It feels painful as a student to spend weeks writing and re-writing just to produce 2 lines of code, but in the end those 2 lines will be doing the work of 20 lines of Julia, or 200 lines of C, and feel like a pure, direct mathematical expression of the algorithm you intend.

This reminds me of what a BASIC programmer friend of mine said about C when he first tried it. After many (mostly senseless) debates, I eventually convinced him to try C after showing some bodged-together flashy graphics demo. He got me to teach him basic C syntax and then took off on his own, writing a game. After a few weeks of hacking, he presented me with a decent Asteroids clone, "I don't see the point of C." Th…
I really wish more people would focus on using/making languages that cater to a strict niche but compile to a sensible and readable common root language/IR.

This well-known J dude has done some: https://www.youtube.com/watch?v=CzK2SazvCxM And J is almost isomorphic to APL.
APL also has support for GUI apps (Windows only) using .NET, but graphics takes some additional effort: https://www.youtube.com/watch?v=iC9floP7POU
