A group of Caltech students heads to MIT to throw down the prank gauntlet. They spend the weekend handing out t-shirts to prefrosh that read "MIT" on the front and "because not everybody can go to Caltech" on the back. During the night they spell out the letters C-A-L-T-E-C-H on an MIT building using a low-power laser. They also hang a banner on the MIT dome, changing its name from 'Massachusetts Institute of Technology' to 'That Other Institute of Technology.' They now await MIT's response. (make sure to check out the page of pictures of the pranks).
