Star Trek: The Next Generation Easter Egg - So Hidden You Can't See 'Em

A few things added to the show that are NOT viewable on camera. Don't try to pause your VCR or anything, it's too small to be legible (but maybe you can get an idea of where they are?).

Dick Brownfield, Star Trek special mechanical whiz whose work on the Enterprise fates back as far as Star Trek's first pilot episode in 1964, tells us that some of the conduits and pipes seen on the original Enterprise sets were labeled with the term GNDN.

Extremely close examination of the impulse drive system schematic panel in Main Engineering might reveal that one of the components is labeled "Infinite Improbability Generation," a tip of the hat to Douglas Adams's Hitchhiker's Guide to the Galaxy.
