Instragram recently made their API public, and a service has been born of this generally accepted to be called "Instaprint" (coined by Engadget, it seems).

Instaprint is essentially a modified Zink photo printer with internet connectivity and tie-ins to the Instagram API, that automatically prints items tagged with any hashtag you choose. For the time being, the company is renting and demoing these "Instaprint" boxes at SXSWi.
