Create Your Own QR Code With an Army of Little Robots

A company called Cross Border Inc. created a fun little program that lets you generate your own QR codes—a 3-dimensional bar code common that can be read by cell phone camera. All you have to do is enter a URL, and the service dispatches an army of little robots that start off standing at random but quickly start hopping into position until they make sense together and can be scanned by IR.
