Back in July when we were in Pittsburgh for the American Malacological Society's annual meeting, my wife and I also visited Wood Street Galleries. There was an exhibit called "Long are the Days, Short are the Nights" featuring a group of artists from Iceland, the country that insists on slaughtering whales.
There were some intriguing pieces, including this one called Rotating Unit by Egill Saebjörnsson.
It consisted of a rotating piece of chicken wire thru which patterns of light were being projected on the nearby wall.
I couldn't resist the temptation to include myself in the display.
Maybe that's the whole point of art.
