Examples for picrate see also JRubyArt-examples (as they are easily translated). Can be autorun with rake. The contributed folder exists for you to add your own (and submit as a PR). Ordinarily we expect users to install these examples with picrate -i samples or for first time users picrate --install which also installs geany configuration. If you use geany as your editor, will be able to run files from the editor, to run individual sketches from command line cd to folder of sketch and jruby --dev your_sketch.rb. Passing the --dev flag speeds jruby start-up.
