Three years ago, as a kind of experimental community art project, Frank Warren handed self-addressed 4 x 6" postcards to 3000 strangers and asked them to mail him back a secret -- anonymously. After receiving about 100 responses, he figured his project was complete. "But the idea spread in a viral way," Warren recounts. To date, the unassuming 42 year-old father has received over 100,000 artistic, enigmatic, and often very personal admissions -- as many as 200 a day. "We think we're keeping secrets," Warren suggests, "but the secrets are actually keeping us. With one courageous decision, you've freed a part of your life."
