gem install toxiclibs
NB: Build is only failing because current version of processing is not available at maven central. This gem provides Karsten Schmidts (aka toxi, @postspectacular) toxiclibs jars for JRubyArt. To compile the gem follow the instructions for JRubyArt. Most parts of toxiclibs API is exposed in the latest version, (but only a few examples are included) in principle it should be possible to make all available!!! For this demonstration I have used up to date source code for version 21, since toxis final release has not yet been released (although Dan Shiffman has released a version for processing-3.0+). There are reported to be number of outstanding bugs with toxiclibs, if they affect you report it here (or better fix them yourself and submit a pull request).
It should be clear that the original toxiclibs is the work of Karsten Schmidt see Copyright
