This was inspired by an art installation somewhere in Sydney, Australia. Random(?) blocks of what appears to be code floats by with an occasional flash of the rainbow.
This is my first time using Processing. Quite fun, but I'm only just scratching the potential of it here.
You can build this with the horrible Processing GUI if you want. But the better way in my opinion is from the command line via processing-java:
processing-java --force --sketch=../codeblocks --output=out --run
and if you want to build a "portable" executable:
processing-java --sketch=../codeblocks --export
