Marco van Zwetselaar@dsmith @naturepoker A big plus of giving a hands-on "how we dunnit" walkthrough is that it doesn't take a lot of preparation.
Recently had several lightbulb moments while Matt Cotten _a l'impromptu_ walked through how he came up with the "Entebbe primers".
It's tough to cater to an audience with huge variance in experience, but with a hands-on demo there's usually something to take away for everyone.
