Processing.js
Project Description
Processing.js is a proposed Mozilla-sponsored project, its main purpose is to wrap Java-based language functions into Javascript. The purpose of this is to use visuals on the open web, using standard technologies such as JavaScript and Canvas.

Project Details
Processing is an open source programming language and environment for people who want to program images, animation, and interactions. Processing is an alternative to proprietary software tools in the same domain.
Processing.js will:
- enable Processing users to take advantage of the full power of the open web
- serve as a forcing function to drive improvements in key aspects of Mozilla products and technologies, including; JavaScript, Camvas Functionality, applications of Bespin, Ubiquity, Multi-Touch and others

- Look at what Processing Java is capable of @ http://processing.org/exhibition/
- Look at what has been done with Processing JS so far @ http://processingjs.org/exhibition & @ http://hascanvas.com/#open-about
- Read Processing articles "Getting Started" & "Coordiante System & Shapes" @ http://processing.org/learning/gettingstarted/ & @ http://processing.org/learning/drawing/
- Experiment around with the Processing Java app, use the Basic Examples @ http://processing.org/learning/basics/ and make something cool, interesting, wacky, where-ever your experiment takes you.
- Test whether you can re-create your sketch by copying your code to http://hasCanvas.com You can share your work so others can see what you have done, you can also use hasCanvas to embed your visualization in your web site / blog.

3D Implementation Roadmap
I have done my best to identify what tickets will block others and have created
a roadmap for integrating 3D into the library. I have done so by analyzing the
Processing site and looking through the Processing source.
Items marked 'fix' have been reviewed but need to corrected.
Items marked 'implement' need to be coded, but it also implies writing a good test.
Items marked 'write test' are done, but need a test before they can be reviewed.
A good test should take a peer-reviewer only a few minutes to check and pass on for super-review.
We still need to address what will happen if a ticket isn't complete. This roadmap needs to be
robust enough to not crumble if this occurs.
Release 0.5
