this is the first time I've seen APL... and I have to say, as a competent programmer who knows a good few languages backwards, I now know what it must look like when my wife looks over my shoulder when I'm coding... total alien hieroglyphics!

APL and C/C++ were my first languages (and that was in a high pressure 90 hour/week trading/underwriting situation). There's a lot of abstraction in APL but the gestalt is closest to scheme/racket, i think. The language lives on in J and K languages, you can read some here

It's not as magical as it seems. Just a lot of single-character, composable functions. You could probably do the same thing in Haskell. (I mean it does look cool but . . .)

but the matrix operations and concepts used in that video is probably beyond a self-taught web programmer (i.e., me :P)
