I decided on a default frame rate of one frame per minute and rendering every 4th frame, so it will progress a bit faster.
There isn't a lot of build progress frankly because everyone else already put in the work. Connect the hat to the Raspberry Pi, connect the screen to the hat, power the Pi :)
Merging the IT8951 controller into the Slow Movie repo was all I had to do. The rest of this project will be mostly framing the panel.
