It’s not exactly what you’d call “high resolution” but this dot matrix display will definitely get your attention.

What a cool… er, hot… idea!

A company called Infernoptix has created large-scale dot matrix computer-controlled displays which don’t use LEDs, bulbs, or any traditional light generation technique. They use fire!

The display is driven by custom software and can operate in several modes including text, sound-sensitive, and freehand drawing. The connection to the computer is via a serial or parallel port with all of the control electronics residing on the display itself.

At 450 pounds and 15 gallons of propane per hour, you definitely won’t be hauling this around to parties, but it’s a neat idea.
