This isn't from the Lego site directly, the Lego Mini Polaroid Camera is a rather wonderful custom set.
It's the work of Chris McVeigh and available from Powerpig's Builds 'n Things as a 99-piece set, complete with decorative decals to get the look of the classic Polaroid. It even has a rear panel you can push to 'eject' a photo tile!
It's sent out in a 'sturdy' cardboard box, with instructions available to download soon via the site. Pre-orders now being taken, with a price of $37.50.
