Very cool, if true

Some months ago I went to see Lawrence Lessig talk in Edinburgh.  While the content of the talk wasn't anything terribly new, the style was fantastic.

This talk builds on that style and is if anything, even better.  It's about the next generation of digital identity, which (to most people) isn't a fascinating subject, but it's absolutely magnetic, and uses technology to great effect.  Next time you see a bad powerpoint presentation, just think back to this and weep for how good they can be.
