The Eye of Sauron

Laptop computer with a built-in web-cam, a classmate doing fieldwork in Panama and tuning in twice a week, a fancy instant messaging package, and a bunch of ne'er-do-wells and hooligans.

Maybe that's why Sauron got defeated in Lord of the Rings. He accidentally tuned into something rather inappropriate while looking at his own Palantir (seeing stone). Kinda makes sense considering a lot of them did get lost. Either that or Pippin messed with the connections :)
