Performance art: annoying as many people as possible, simultaneously.
When I was in engineering school I took a class in Electromechanical Devices, which was in truth a joint project between the School of Engineering and the School of the Arts to see what odd things artists and engineers could create when working together. There were actually some really cool things that resulted from that- and some utter flops.

The first project was to make something involving a crank that you turned that would cause something to happen. We were not teamed up with anyone yet, so it was art students versus engineers. We had one guy who made wire gears and linkages to simulate the valve train on an engine (yes, he was an engineering student), another who made a clock tower with a Harold Lloyd figure dangling from the hand while a pair of wings flapped... the results were all over the place, and really pretty impressive. We had them all set up for critique, each of us explaining our pieces and demonstrating them.

Then it was Tim's turn.

He led us into a room where there was a cylinder standing with a block stuck to the top edge and a plastic stag sitting on top. On the floor next to it was a fashion ad with some model simpering with glossed lips. He switched off all the lights except for one that shone down on the cylinder.

Tim then took off his shirt to reveal a white tank shirt, then sprayed cologne over himself. He knelt by the cylinder and moved the stag to the edge of the block, then turned a crank to unwind some string and lower the stag toward the photo. It stopped a couple of inches short. He cranked it up and then down a couple of times, then began biting chunks out of the block and spitting them on the floor, working with manic intensity to gouge a deep groove in the styrofoam block until when he turned the crank the nose of the deer kissed the photo. Then he arose and left the room.

The silence was broken by someone asking, "Can we lock the door before he comes back?"
