I always heard them referred to as an "Idiot Box." Neon relaxation oscillators are fun. Such a device can be built where the lights blink in random patterns, or they can be configured to flash in sequence.
90 volts worth of 9v batteries is expensive, and a true B battery cost even more. I tend to use a simple oscillator feeding a backwards filament transformer, thereby getting the needed 90v from a few AA cells.
