I saw this on twitter a month ago (thanks to Lucy Richard) and just back to it now. Take the Wired founder and a technologist who hung out around the Space Shuttle program, set the location as San Francisco and then film a number of slots with BoingBoingTV and you end up with TCHO.
Part one covers the origins of chocolate and explores the sensual side of the beans and the product. For more click through to youtube.
Enjoy it, Keith
