I’m hoping you add the MakeCode TV project to the list of projects that are built into Kiosk mode. Then, run it on all of the kiosk machines in the office. Make sure it plays ridiculous songs during the commercials. Tell Jacqueline that you’re just testing the synchronization routines to make sure they’re as accurate as possible.
Oh … and have an “auto changer” mode where the channels just randomly change at random times.
