Hi HN! I know this isn't the usual HN project, but I remember seeing something like this posted for a snowstorm a while back. I'm in CT and since I was locked in my college dorm yesterday as Hurricane Sandy made landfall, I decided to get some like-minded people together and design and sell a T-shirt to help the relief movement as the storm continues its path. We will be donating 100% of our proceeds to charity (currently we're looking at AmeriCares[1], but please let me know if you have any suggestions).
Technology wise, I set the entire thing up in a couple of hours with a static page and put it up on an AWS S3 bucket. We're collecting the orders in a PayPal account now to build up a large order and then getting our shirts printed, allowing us to minimize our printing costs as much as possible.
We're selling our shirts for $14 (free shipping) at http://www.shirtsforsandy.com. Even if you can't buy a shirt, we would greatly appreciate it if you donated a few spare dollars to the relief effort or if you could spread the word about what we're doing.
