While I'm debating on what hardware to buy I decided to do a simulation of the rotating display in Unity. The above gif shows how it's working so far. It took me awhile to get the math right to correctly sample the camera feed. I had to take a center point and then do some trig. based on the current rotation of the display. This example is using 72 pixels with 3 displays rotating simultaneously. I'm pretty happy with how it is looking in Unity and want to get a physical display going!
I've also been testing how fast I can send data between Unity and the Arduino. My current plan is to send Colors in Hexadecimal format and include an integer to determine what pixel it is for.
