Picture of the Day: Patent for a Fiber-Optic Christmas Tree

More

Nothing says Merry Christmas like the sparkly cheer of fiber optics. This patent from 1973 is one of the earliest of many for various fiber-optic Christmas tree set-ups. As the inventors, Albert V. Sadacca and Bernard Paulfus, both of Illinois, explain, "Recently, ornamental or display lighting and lamps employing optic fibers have become quite popular. ... This invention provides an artificial Christmas tree employing a fiber optic illumination system which takes advantage of the lighting effect of a pin point-like spray of lights."
