its actually already on EVERY non colored LCD screen that you use, like calulators, some cell phones, the clock and odometer in our cars. what you do, is you take the original film off, its on front of the glass. then you take the new piece you cut out, and turn it 90 degrees to the angle that the other piece was......youll notice the screen turn black. now, when you put everything back together, and plug, lets say, the 6th gen's clock back in, itll light up the numbers unsted of the background.
so say you have a white LED lit clock in your 6th gen (i personally took the cruise control on/off indicator light and put it in the clock), ok so you have a white LED lit clock, you do this polarizing film process that i just described, and you install everything back to the way is was. so insted of the clock NORMALLY lighting up with a white background and black numbers, itll like up with a black barckground and white numbers. ill post a pic of my clock tomorrow. i took one on my cell, but its a cell pic, haha, so its not that great. ill show you guys tomorrow night what it looks like.
