Very cool! I don't know about outside durability as this stuff is marketed for use in computer cases, which are usually indoor pieces of equipment, but there again, undercar neon tubes are fragile also. I do know that I would love to see this stuff on the interior of my car, and the DC current it requires (although I am not sure about voltage) would be easy to install in the car. Thanks for the info! I am sure many will appreciate it.
