Inspired by Google’s recent promotion of QR Codes, I thought it might be fun to experiment with encoding a Crossref DOI and a bit of metadata into one of the critters. I’ve put a short write-up of the experiment on the Crossref Labs site, which includes a demonstration of how you can generate a QR Code for any given Crossref DOI. Put them on postcards and send them to your friends for the holidays. Tattoo them on your pets. The possibilities are endless.
