David John Andersson's senior thesis is called "This Train Is Not a
Playground: Improv Everywhere and Urban Public Pranks"
(<http://socialstudies.fas.harvard.edu/icb/icb.do>Harvard College).
It's a splendid piece of cultural analysis of contemporary urban
hacking and guerrilla communication. David even won
<http://secfas.fas.harvard.edu/icb/icb.do>a prize for it in 2009.
David interviewed tons of interesting people from the field: Scott
Beale, Hans Bernhard, Iain Borden, Chicken John, Mark Dery, John Law,
Howard Rheingold, Joey Skaggs, V. Vale and -- yours truly -- Johannes
Grenzfurthner of monochrom.
The paper is not available online, so I simply decided to host it
here at monochrom.
Enjoy!
