I have been looking for Processing sketches and libraries that generate Gcode (machine code used for CNCs) for a while now.  A couple months ago I found Agata Guzik's PGCode3D library created as part of her 2009 thesis work.  It looks wonderful, but it seems that the file has disappeared from the file sharing site where it was hosted. The downloaded file is 20bytes and impossible to unzip.

I've looked around a bit for a file elsewhere on the net, but to no avail.  Does anyone out there have a copy of this library or a link to other Processing projects that generate gcode?  I am curious how much I will be writing myself over the next couple of months...

Thanks for the help!
