Unfortunately, the place to start is advertising your display on craigslist or ebay in hopes of finding someone with a broken Nino: it's designed to be run by a controller chip that sends individual screen dots to it at very high speed, and the Arduino just can't do that.
There are some graphic LCDs available that have a controller chip built into the module, and some folks have developed Arduino software to drive them: see the GLCD library
. They're available on the surplus market
for as little as $10 (for a smaller, black-and-white screen).
Another possibility would be to buy an old iPaq or Palm, and connect to it via the serial port. There's an application called palmorb
that makes the Palm emulate a large character LCD, and something similar could be done to turn a PDA into a graphics display.
