Great site!  I think we have very similar tastes and sensibilities.  I've also created a free, minimal tool that people can use to accept bitcoins.  Mine is geared more towards merchants who would run it on an electronic device to accept payments in a store or restaurant.  The page does currency conversion and monitors for transactions at a provided address by listening to a websocket from blockchain.info.  When a transaction is detected the page displays a notification in real time so the merchant can know that payment was received.

The URL parameters are configurable so you can enter any receiving address.  You can use a form to configure other parameters: http://vanbtc.ca/setup or save the parameters to a persistent URL by creating a username and password: http://vanbtc.ca/users/new

The page is all done in javascript but the persistence code was done with NodeJS.  The code is lumped together with the rest of my vanbtc.ca website but I'm planning to extract it into a standalone tool and release it soon.  For now it's available here: https://github.com/asoltys/vanbtc.ca

I'd be interested to hear your feedback!
