I have bought a number of mounted film cells (ie, individual frames of film cellulose from a movie) and want to frame them and put them on the walls of my home cinema. The problem is that when these cells really need light behind them in order to be seen clearly and so I need some way of putting them in a picture frame and illuminating them from behind. I have had an idea which involves building a shallow box frame about 1/2" deep and putting a miniature lightbulb and fitting inside the frame along with a battery, connected to some kind of bellpush on the outside bottom of the frame so that the film cells were illuminated when you pushed the button. [I have ruled out the idea of having a light inside the frame permanently on due to the possible heat risk of melting the film cells] I was thinking along the lines of all the pieces from a small torch (minus the body) connected through the frame somehow, or maybe bits from a kiddie's electronics kit taped up inside with a common/garden bellpush on the outside from B&Q. Anyone got any idea where I could get the bits from for this? Or if there would be a more elegant solution to my problem?
