I have been playing around with 320240 displays (ILI9341, about AUD$10 worth). I have a couple of 480320 displays on order and I saw lots of these....

for about AUD$25. It seems to be controlled by one RCA video cable.
Anybody programmed one of them? Or any pointers on how to do it?
It seems fast enough etc for motion so would be a nice display to play with Mandelbrots etc.
I have been using Nanos and Dues.
