I've just mounted my pdp-504 on my living room wall (a HUGE improvement over the table top stand!). I've got this idea of back lighting the screen, by putting coloured light tubes either side of the screen between the screen and the wall. I think this could have a very nice effect, perhaps using blue cold cathode tubes? Has anyone done something similar? Also, where can I get some suitable lights? I looked in Maplins but they only do Cold Cathode tubes that run off either a PC power supply or a 12v car system. Does anyone know of somewhere I can obtain mains-powered Cold cathode tubes? Cheers, Mat.
