A Sketch, a Link, a Quote, and a Video
That blank black rectangle on the left is waiting for you to move your MOUSE (or finger) around in it. To stop at any time, just move your mouse out of the box. This is a very simple and wonderful script from this page of beginning Processing tutorials. AND here is the sourcecode for the simple sketch at the left
NOW for the QUOTE:
If you tell me how you draw, I can make my machine do it. --Georg Nees
AND NOW for the VIDEO
This Ultra_Lab video, which is currently on the homepage of processing.org is marvelous. It really is about all things digital, but ends up with data and art. Watching it will be 40 odd minutes well spent.
