It's crazy how little is happening in school nowadays. With AP tests over, half of every school day is a study hall. Gives me plenty of time to work on this project.
Anyways, I've been implementing the GUI, linking controls and commands and functionality. For example, I can select which serial port and projector to use, and the layers shown in the preview window are based on chosen settings.
But there's not too much more to show off (it all looks the same as yet), but big things are coming.
