I cobbled "BrickBuildr" together using phpFlickr as a way for the AFOL [Adult Fans of LEGO - Ed.] community to share "LEGO only" pictures with one another (for those who had Flickr accounts). [There's also] a way to browse new "LEGO only" photos from your iPhone.
He's selected only certain groups from within Flickr that feature AFOL creations instead of simple just every photo tagged with LEGO. Looks like a great project for finding new builders you like. And by joining one of the groups included, your creations will be automatically slurped up, too.
