The RQRCode gem does all of the QR Code generation magic. I manipulate all the code with some CoffeeScript and jQuery. RQRCode itself is a port of a JavaScript library: http://www.d-project.com/qrcode/
I've written some stuff locally that'll render the QR Code into canvas and provide a download link using a dataURI but it's fundamentally different than the table/css manipulations I'm doing right now...and well, I have an infant at home, so the site's being neglected ;) PM me on github if you want that chunk.
