The unzip peasycam version needs to be updated to match the downloaded version.
This is my first look at processing.py and I'm quite impressed, I had to extract the 64 bit binaries to get the opengl sketches to run on my linux box (however they run fine). This is intriguing because I can only run opengl sketches on ruby-processing when full screen (on said linux box). I've an idea to create a bash script say pyp5 to run samples, then perhaps a commando file to launch the app from jEdit as a kind of ide?
Now done see gist
Worked for me
