365/64: Yes, Yes, Yes! by Yoko Ono

Cameras are positively encouraged at the Museum of Modern Art (MoMA), though I don't see the point in photographing the artwork itself. I saw this delightful little scribble on the floor that intrigued me so grabbed my camera, only to be approached by a security guard. Uh oh, i thought, but all she wanted to do was tell me the little scribble was by Yoko Ono and she had written about 18 little notes all around the building. I only found four but it was a really fun treasure hunt.
