I remember seeing a video of a light display in Cuba. They couldn’t get much in the way of controllers so they used a rotating drum of electrical contacts to open and close circuits for animation effects. This looks very similar to that. Pretty ingenious but totally unsafe.
The media that they choose to consume is the problem. It plays down the accomplishments of “the enemy” and plays up the hardships and failures like “rampant illegals” and constantly rising food prices. I blame “stupid Americans” less than I blame manipulative billionaires that control media consumption.
