Heres what im trying to do: Basically, I want to find a way to create a device that will have an input for audio (preferably a 3.5mm) for an mp3 player and an output to go out to an amp and speakers. Here's the twist - that device also uses software (something like milkdrop for winamp) and pushes a real-time visualization to a bunch of color screens. The screens I have are color gps screens, phone screens, gameboy screens...basically a ton of little LCDs salvaged from a bunch of consumer electronics over the years. So, as you play the music, all the little screens play the same visualization. Im looking in the ballpark of 10-20 of these little screens. I posted here because im not sure if theres a better way, or if theres a product out there that I can buy or modify. Maybe some of you have used a multi camera set-up that could be incorporated into my model somehow. I'm also open to using other kinds of screens if they can be modified easier.
