Matrix rain

The effect has been clubbed to death, but I had to give it a whirl in ClojureScript.

You can see the live demo here.

Goals

• write idiomatic Clojure without mutation shortcuts, so no object-array and such
• zero dependencies, so no Quill, clojure.core.matrix, etc
• tight code without getting (too) obtuse
• visually close to the movie rendition

Setup

To launch the project and enter a REPL:

clj -m cljs.main -c matrix-rain.core -r

For an optimized build:

clj -m cljs.main -O advanced -c matrix-rain.core

then open index.html which will load the optimized out/main.js.

Enjoy!
