Sketch.js started as a personal JS library for creating canvas experiments
in the browser. The early version is a hacked together (not working in
some areas) prototype specific to the examples sketches.
The early version is archived in the early-version git branch for reference.
The first prototype of Sketch.js was started in August 2011, was slowly worked on for about a month, than put on the back burner to pursue other projects to strengthen my JS skills in building what was becoming a fairly complex project.
Over the last 5 months I've developed JS workflow I'm comfortable with, written a handful of npm modules, and studied numerous design patterns. Finally feeling comfortable with my toolkit, I am committed to this project again and hope to share it in the open as soon as it's mature enough.
Much of Sketch.js is directly inspired by Processing by way of Processing.js and the API borrows heavily from Paper.js / Scriptographer.
Sketch.js would not be possible without all of these awesome projects. Each of which has been a invaluable tool in learning computational drawing, programming animation, and experimentation badassery.
The turning point in forming Sketch.js as a project came from attending Eye Festival 2011. At the current time (June 2011) I had taken a year long break from programming entirely to focus on illustration, design, and general creative arts. Feeling revived and totally inspired by this game changing conference, I reentered my interest in programming and began gather the resources in creating JS Canvas library.
In its current state, Sketch.js is intended for nothing other than general experimentation with the html canvas element.
Near-future versions will support the same (or similarly refined) Sketch.js API for generating images via node-canvas.
