I found this while looking through some sketches from college (graduated from the Cleveland Institute of Art 1 year ago). I've been meaning to get back to Processing for a while. This went on to become an interactive installation, wherein your face was mapped onto the ball and any noise you made would propel it forward. That won't work on OpenProcessing, so I thought I'd upload the original inspiration instead.
Eternal thanks to Prof. Nicholas Economos. I did this for one of his classes, and it became the inspiration for my BFA Thesis project.
