Saul Griffith shows some howtoons, along with some video of kids enjoying building things.  Howtoons are coming out in books soon.  He says 10-year-old boys all want to build flying skateboards.  Ten-year-old girls all want machines that will allow them to see their friends' dreams.  He hopes some of those girls will grow up to be neuroscientists.  He talks a lot about liability risks.  In the question period, people talk about how to scale Saul's operation (he does evenings at science museums for kids). Someone points us to sas.org.

In general, everything SquidLabs is cool.  Take a look at instructables.
