Fantastic Voyage, revisited

For those too young to remember, in 1966 a film named Fantastic Voyage was released, starring Raquel Welch and some other people. The premise was that, in order to save a patient, a submarine containing a medical crew was miniaturized and injected into the patient. It's still a pretty watchable movie, although some of the special effects haven't worn too well.

Anyway, I remember thinking when I was watching it several years after it came out that it would make more sense to just miniaturize a camera and surgical instruments, and have a doctor control them remotely.

Now they've done just that (with the camera at least). They've still got a ways to go before it can travel the bloodstream, but it's still pretty cool.
