Get it here GitHub - jashkenas/ruby-processing: Code as Art, Art as Code. Processing and Ruby are meant for each other. the release has
been updated to jruby-1.7.5. Of course this only affects the vendored
jruby-complete, so you should also update your installed jruby-1.7.5 (if
applicable) to gain full benefit from the update. If you get complaints
about the bit versions for java check your config file .rp5rc.
