From ffffound to Behance Network to WordPress to Flickr, I clicked across the sketch trail of a concept tinkerer.

There are a number of sites aggregating jolts of inspiration and its fascinating to observe how potential fans and feedback can emerge for napkin ideas. Related, here's a nice video visualization of Python's evolution (part of an experiment called code_swarm visualizing the collaborative creation of open source applications).
