Didn't you describe it as a "hello world project hooked up to a random number generator" at some point? ;-)

I do recall that Patrick has written a supposedly-neat A/B testing framework - is that what you're referring to?

[I'm not trolling, just honestly curious!]

The bingo card generator is, in a sense, "hello world" hooked up to a random number generator. The mechanisms built around that small piece of software to demonstrate and provide value are what's sophisticated about BCC.
