Thanks for the response. My question wasn't really directed at you—I can see all kinds of ways you could justify the project, including just curiosity. My question was for the people who are putting money on the card.
I hope one of your other ideas works! Good luck! But I suspect a big part of the impetus behind the contributions is a feeling of reciprocity, which is a different impulse from charity.
