Well, I demoed at the Makers Fair yesterday morning.  Glad it was morning because later in the day the heat rose and we were on OMSI's huge parking lot.

I was there as part of the Creative Metal Art Guild's participation.  I had never heard of it before.  There were many booths dedicated to reusing all kinds of detritus, making robotics, Viking role-playing and weapons manufacturing, and best of all, food and beer carts!
