A company called Lumilor has announced a permanent electroluminescent paint that can be selectively illuminated by applying a charge to it. Burning Man attendees are already familiar with the ubiquitous, cheap EL wire, but this takes things to a new level:
The LumiLor TM electroluminescent coating system is a patent-pending, practical, durable and affordable technology that can be illuminated with a simple electrical current.
Used in conjunction with simple driver electronics, LumiLor will illuminate any surface brightly, and is capable of being custom-animated to flash in sequenced, strobed, and sound activated modes.
The potential for customization is practically limitless!
