We are about to switch to a new forum software. Until then we have removed the registration on this forum.
ruby-processing-2.2.0 is now available from github, it is based on processing-2.0.3, and uses the latest version of jruby (jruby-1.7.5). Included with the download are more than 330 worked examples, the majority translated from vanilla processing and the contributed processing libraries (toxiclibs, fisica etc). As with other ruby projects ruby-processing is distributed as a gem, unfortunately the built gem is too big to be hosted on rubygems, but the build/install process is very simple. The beauty of ruby processing is that you can in the main use most of the ruby language (version 1.9.3/2.0) including gems (eg MDArray, which is similar to numpy) and also the processing java libraries. So you can have the best of both worlds.
