Photos on grass

UK artists Heather Ackroyd and Dan Harvey "printed" photographs on grass. This particular piece was an advertisement installation at the 2008 Wimbledon Tennis Championships. From Creative Review:

The artists essentially use grass as a form of photographic paper, projecting a black-and-white negative image onto a patch of grass as it grows in a dark room, and using the natural photosensitive properties of the grass to reproduce photographs. As Wimbledon is the only remaining Grand Slam tennis tournament that takes place on grass, it was a natural fit for Ackroyd & Harvey's work, which has also appeared on the National Theatre Lyttleton flytower and Dilston Grove in Bermondsey. For this work, they photographed three people at Wimbledon prior to the tournament, and displayed the resulting grass versions of the photos on three large panels in Merton Park, where the tennis fans have been camping and then queuing for tickets this year.
