Was thinking 15h of lectures, ~20h optional TA tutorials over 5 day period. Undergrad level stuff, as it's not for academics, but interested amateurs and we go home after a week with something to work on, maybe come back for another session once a year.

I'd ask, would you pay $5k to hang out in a yurt on Anegada for a week and learn an undergrad intro to category theory?

Equals...awesome?

Other appealing ones to me would be from a selection of:
