Some friends in San Francisco sent me this one - a fun outdoor campaign that the San Francisco Zoo is doing that has people all over the city imagining what it would be like to have wings, horns, spikey ears, feathers and lots more.  Its a simple (which are always the best) effort, with a vaiety of animal parts showing up on bus shelters and walls - positioned in a certain way so people can stand in front of them and take photos to share with friends.  The campaign provides a simple reminder of the fun waiting everyone at the Zoo, engaging consumers and creating conversations to build buzz and excitement.
