Remember the red blinking lights device?
This silly device made it into most of the Star Trek movies and modern TV series. I always loved seeing it in the background. But, the device receives its first true mention in the sequel to Airplane. This device prop/device crosses over to many sci-fi universes and I love that.
Here's some information on the red blinking light machine. You can rent this device for parties for about 800 bucks here.
This device has no purpose.
