Atlantic is the next major rewrite of the Zajal creative coding framework. It is built on ClojureScript, Pixi.js, ThreeJS and the ongoing progress of the Arcadia project. The goal, as always, is to create a highly expressive, completely live creative coding experience suitable for beginners and advanced programmers alike.
This fourth rewrite, continues the exploration of Clojure and Lisp in the service of creative coding, but builds on a web-based stack of functional reactive tools that have become practical in recent years. This incarnation of Zajal, like the previous one and the Arcadia project, experiments with the effects of functional programming on high performance interactive graphics programming. The hope is to provide a real semantic alternative to the imperative painters-algorithm style tools available today.
Extremely early, nothing beyond the basic concept has been demonstrated to work.

The trajectory of the project is towards a functional approach to creative coding that uses a "virtual scene graph" representation akin to React's. The current implementation is faster than any other similar technology for our purposes and can target the HTML DOM, ThreeJS scene graph, Pixi,js scene graph, or any other mutable tree-like data structure. The current prototype a minimal JavaScript Electron application that loads ClojureScript and sets up a socket REPL and filewatcher.
Electron needs to be installed.

This project has been generously supported by the following institutions. They believed in it, challenged it, and pushed it forward. Zajal would be nowhere without them, and I thank them all deeply.
- Parsons The New School for Design, where Zajal was my thesis project towards an MFA in Design and Technology
- Karaj Beirut, where Zajal was the focus of my residency
- Eyebeam Art and Technology Center, where Zajal was part of my fellowship exploring code as self expression
