The Face2face project. JR, an "undercover photographer", and Marco, a technology consultant, had 41 people - israelis and palestinians - mugging for the camera and plastered the huge, unavoidable pictures on both sides of the Israeli West Bank barrier, pair by pair : one israeli, one palestinian, both having similar jobs and posing in a similar fashion (+an imam, a rabbi and a christian priest). See also the trailer (YT, other videos available on the main site).

StreetMattress.com - Much like "found art", this site chronicles the phenomenon of abandoned mattresses, and finally gives the public a forum on which to comment on them. Some if my favorites are here, here, and here.
