San Jose Semaphore Cracked

BoingBoing reader Jonathan says,

Last year at theZeroOne digital art festival artist Ben Rubin unveiled the "San Jose Semaphore" atop the Adobe tower in downtown San Jose, CA. For a year now, the four rotating LED wheels perplexed everyone who saw it.

The answer to riddle of the wheels has been revealed. The Adobe building is transmitting the entire text of Thomas Pynchon's "The Crying of Lot 49." A very appropriate choice for Silicon Valley if I do say.
