One of the other activities available for non-gamers was some basics of Kendo instruction. It was real basic, to be sure, but still interesting and informative.
Also, on another note, this will likely be the only update today. I'm posting this on Sunday, which is the end of the Con, and time to head home, so you likely won't see anything until at least Monday. But keep checking back, as I still have more clips and things to post.
