 Example-Sketches
 ================
 
-Many of the vanilla processing example sketches have been translated to ruby-processing, and they are mainly written as 'bare' sketches (ie not class wrapped) in keeping with the original processing.  At runtime these sketches the get wrapped into a Sketch class. Should you prefer you can still write class wrapped sketches, these will work equally well with ruby-processing. Certain sketches must be run with JRuby-Complete (`load_image` and `shader` sketches), this is a java permissions thing with jruby. You should also checkout the [Nature of Code Examples in ruby][] and for the beginner [Learning Processing with Ruby][] for even more examples.
