A possible change in attitude started when a TARDIS, which hackers had placed on the MIT Little Dome (August 25, 2010) and the MIT Great Dome (August 30, 2010), was transported to the roof of Baxter Hall at Caltech (January 4, 2011) by MIT and Caltech pranksters, where it remained for several weeks. The traveling time-machine subsequently reappeared atop Birge Hall at the University of California, Berkeley (January 29, 2011), and then rematerialized on the Durand Aeronautical and Astronautical Engineering Building at Stanford University (March 18, 2011). The TARDIS came complete with a helpful note explaining how to disassemble it, and suggesting passing it on to other unexplored destinations.
