Vim fans can quickly create/modify and run sketches in JRubyArt first:-
mkdir my_sketch cd my_sketch k9 -c my_sketch 200 200 # creates an outline sketch vim my_sketch.rb

NB: make sure
eol line exists at end of script
Here is the resulting sketch run from vim using:-
:!k9 -r %
Close the sketch and you are returned to vim editor.
