An FFGL effect that shows your clip on a split-flap departures board. Every cell is a drum of flaps that can only turn forwards, one flap at a time, at the motor's rate, and every flap in the air is a hinged plate falling under gravity and slapping onto the stop. A change ripples across the board, a step brighter is one flip and a step darker is the whole way round the drum, a moving picture is never finished, and the drum can be printed with tones, a palette or a message.
This demo runs the plugin's shaders in your browser, so it needs JavaScript and WebGL2. The plugin itself, its source and its downloads are on its repository.
