In the 1950s, folks didn't have snazzy LCD displays, but they did have cold cathode neon readout tubes. Let's take a look inside one of the more popular brands of these tubes - the NIXIE - and marvel over its clever design.
These photos are from a teardown conducted by the folks of Evil Mad Scientist Labs, and they show the inner workings of a nixie tub - complete with the little stacks of numbers. You can check out more photos and learn more about the magic of these old-school displays over on the Evil Mad Scientist site. [Evil Mad Scientist via Core77]
