I have always been interested in Processing, the open source project that, according to its website,

…is an open source programming language and environment for people who want to program images, animation, and interactions. It is used by students, artists, designers, researchers, and hobbyists for learning, prototyping, and production. It is created to teach fundamentals of computer programming within a visual context and to serve as a software sketchbook and professional production tool. Processing is developed by artists and designers as an alternative to proprietary software tools in the same domain.

I read Ben Fry’s blog and his book is on my Amazon.com wishlist.

Now, John Resig has created a Javascript API for Processing. Expect a lot of more use of Processing on the web.

I modified one of the demos to use some IDL example data.
