Now, this isn't available yet, it's not a real product yet, more of a concept BUT...this would be huge if they actually came out with it.
It's an INSTAGRAM camera that would operate much like a Polaroid camera does. You can take pictures, use one of the Instagram filters to alter them, print them out, BAM!
It's a concept of ADR Studios and they have a FULL BREAKDOWN and MORE PICS on their site
