Some time ago I posted a video of a very neat Geometer's Sketchpad sketch simulating Theo Jansen's beach animals. However, I didn't investigate the source of this effort.
Today, I read Barbara McLaughlin's post which embedded the video of Theo Jansen's TED talk, below. Astonishing what problems the human mind turns itself to. As Barbara points out this is the kind of delight that is a reward for maintaining a Personal Learning Network.
