Barcodes are really cool. This guy's apparently historical site generates barcodes for numerical values which are mostly used in retail stores, but new "symbologies" have arisen since then. Some (Code 39 and Code 128) can translate alphanumerics, which is way fun (you have to specify the 'T' parameter as either of the aforementioned symbologies)!
I admit it: The new version of XScreensaver inspired this post.
