This segment of the great "Penny Arcade" comic strip had a link to an essay by Philip K. Dick, which makes for some strange reading. After that, I didn't recall when or how he had died, so I looked him up on Wikipedia. There I discovered that after his death, someone had made an "android" of him for exhibition, that somehow got its head later lost by an airline.
Legal fun ensued. The head, despite being missing, ended up starring in a BBC radio play.
The PKD android in "action." From there, I drifted into his interviews, and a Bjork video...
I go through some variation of this process dozens of times a day.
