Re: What Non-Fiction Book have you just finished?
I have just rererereread Impro by Keith Johnstone, it's the foundation text of Improv (excluding Spolin's work), and a minor work in the field of the anarchic teaching method. It's games and concepts work really well with in a role playing situation as well. It's Mask stuff was so interesting when you compare it to LARPing that I ended up loaning my copy out to the key creators of a big Kiwi LARP. The book itself is written as one of those semibioographic, semi academic works that Theatre uses. All in all, yeah, it's pretty sweet.
