David Rosen's World Of Goo Design Tour
My eight-second attention span means that I often go to post stuff four or five times before I make it all the way through to the moment of actually typing it into the RPS interface, and this video by David Rosen of Wolfire is once such much-delayed info-trinket. Thanks to the half dozen people who forwarded the link!
