MIT's Great Dome is a prime hacking target since it graces all of the school's admissions brochures. Students often scale the 150-ft. high building and deposit an object on the rounded roof, including a working phone both, a fake cow, a piano, a small house, and a police car, tagged with a parking ticket reading "No permit for this location." Other pranks have taken advantage of the dome's shape. One year, students topped the dome with a propeller, then added a red cloth stripe down the side so the dome resembled a giant beanie. Another year, students topped the dome off with an enormous pink nipple so it looked like a giant breast. And for the 1999 release of Star Wars: The Phantom Menace, students used colored fabric panels and black paint to make the dome look like R2-D2. Brilliant.
