Polanoid, an online flickr-esque community of polaroid photographers hosts a lot of interesting projects.
The current one,
Unmade Beds (based off the new
independant film) is a collection of polaroids that exhibit "the remains of *your* passionate, eggziting, boring, sleepless, sweat-soaked nights."
BUT. That project aside, one of my favorites was the
Endangered Analog Species Project:
"Let this project be a tribute to all those analog goodies whose right to exist is endangered by their digital successors - vinyl records and their players, analog phone booths, dial plates, typewriters, Scopitones, Gummiringerln, the Rodox magazine, ... you name it, you shoot it, we celebrate it!"
