Interesting stuff at the Game Developer's Conference (GDC).  Josh Rubin's Cool Hunting spied this cool stamp that embeds personal info into a cameraphone-readable format that can be easily imported into mobile phones.  If IR was just easier, would we really need this?  I don't know but it's still pretty nifty.  Reminds me of those EyeCat? wand-thingies that Radio Shack and others were giving out where the idea was you'd scan an ad in a magazine and visit the website.  Er... nevermind.
