One of the more scary "Outer Limits" episodes was O.B.I.T.
From the opening intro by the Control Voice:
"In this room, twenty four hours a day, seven days a week, security personnel at the Defense Department Cyprus Hill's Research Center keep constant watch on its scientists through O.B.I.T., a mysterious electronic device whose very existence was carefully kept from the public at large. And so it would have remained but for the facts you are about to witness…"
Looks like the NSA is building their own these days.
And be sure to read some of the comments. Looks like there's a bunch of "us" among the geeks who read WIRED.....
