It was functional for me; there was someone reading some rather bad (in the best way) jokes, "What kind of car do dogs hate? A cor-VET".

I saw a comment above about having a radius visible for the talkie (if there is a radius?)

Oh, and +100 points for the thing being anonymous.

It works, people are shy. I had a crack at talking to some folks, more to comment on how interesting the application itself is. I wonder how the app deals with many people connected? Maybe different instances?
