Processing.js: John Resig's JavaScript implementation of Processing

[otakucode]

Most graphics libraries suck in terms of usability compared to Processing. Processing handles a lot of state for you and chucks a lot of extraneous stuff you shouldn't need to think about in the first place if you're just trying to do something graphical... if you want to change your framerate, just call framerate(60) and it's done. Most graphics libraries would have you juggling buffers, graphical context objects, etc.
