Video projection.

[The_IndustrialPhreak]

So I know I probably will not get a very  good result from this but I picked up a 35mm slide projector this weekend for a project. Its a Sears and robuck tower model 3500 slide projector and I am thinking about experimenting with putting one of these oled displays or a TFT in the light path to roll my own video projector. is there anyone in our group with experience writing code to put SD video signals through this? http://www.adafruit.com/products/1431

That particular board doesn't look like it's transparent, so you may have a hard time getting it to work in a projector.  An LCD would be easily converted by simply pulling off the backlight and diffuser layers, but is the same process possible with OLED?  From what I know of their operation, they're self-lighting and there's no reason they should be transparent unless they're specifically sold that way.

Aside from that, you'd have to figure out video over SPI.  I don't know anything about that, but I think it's a fairly ambitious task to get good framerates on this type of display.  You also won't get anything resembling SD video out of it, since at 128x128, and SD is generally considered 640x480.
