Got a nice tip from Jason Sundram (thanks!) as a followup to the screensaver theme:

@mariuswatz websaver awe.sm/5daM6 is a great way to use a processing.js sketch as a screensaver. Here’s mine: viz.runningwithdata.com/boids/

Websaver runs on MacOS and allows the user to specify a web page to load when the screensaver is active. And since it uses Safari to render the HTML (I assume), you can use HTML5 and Processing.js to run computational sketches on that web page.

It’s a nice hack to enable easy development of screensavers based on open web standards, without having to worry about interaction with the OS etc. In fact, it’s nearly as good as my Google Chrome screensaver idea, minus an app store etc.
