We got another chance to interview Friend of the Hole and rockstar game designer Jonathan Tweet, whose magnificent book Grandmother Fish comes out today in his new deal with Macmillan. We’re going to the launch party at Ada’s Technical Books in Seattle on Saturday 9/10 from 10am-2pm, and you should too.

In the interview, we also got to talk a bit about Clades, a game Tweet is designing to teach evolution to kids and their adult companions. We played a bit of his early design and had a great time. We’ll let you know when he fires up that Kickstarter next month.
