Recently commuters in Southern California may have noticed small but official-looking brown signs that read "ISLANDS OF LA NAT'L PARK" around the city. The signs also direct the inquisitive to the URL http://www.islandsofla.com/. There visitors will discover that an artists' collective is designating traffic islands worthy of more attention from busy urbanites. Participants in the project are encouraged to upload photographs of these micro-oases and geotag them for an area map on Flickr. A blog explains the group's rationale further.
