An FFGL source that puts the Test Card's pumpkin patch into Resolume: a jack-o'-lantern on every LED tile, each carved with one of six faces, its candle flickering and its face blinking, winking or chomping in its own time. It isn't a pumpkin like the test card's, it's the test card's pumpkin: the drawing, the timing and which face lands on which tile are its code, ported line for line and checked against the test card itself, so the same seed and tiles deal the same patch. Set its clock to the wall and it flickers in step with a test card on another machine.
This demo runs the plugin's shader and a port of its CPU half in your browser, so it needs JavaScript and WebGL2. The plugin itself, its source and its downloads are on its repository.
