Kidding aside, there are some interesting theoretical results about
ciphers that utilize a plentiful, publicly available source of random
bits. See:

I think the "Rip Van Winkle cipher" was mentioned in Schneier's Applied
Cryptography. Also, I vaguely recall another news story (1999?) that
reported on an encryption technique that hypothesized a stream of random
bits generated by an orbiting satellite.
"Quasar encryption" is likely impractical, but there could be more to it
than you think. However, I did think "web cam encryption" was funny. :-)
