Update since the last post, I have posted a few more examples, catch the latest example  here. One cool thing to note is that since ruby-processing version 1.10 it is sufficient to have the java libraries installed in your sketchbook/libraries folder ( ie you just use your regular vanilla processing libraries in ruby processing). I anticipate issues during the transition to processing-2.0, but that will probably affect a lot of libraries/examples. However toxiclibs will be affected less than some other libraries.
