Bad Apple!! Demo running as a SerenityOS (https://serenityos.org) demo.

Technical details: Regular userland application that loads the pregenerated frames as PNG images (Serenity's PNG implementation). The music is played by Serenity's FLAC implementation, where the main process spawns an aplay (audio player utility) subprocess. A/V sync is pretty terrible, even though I already shifted the audio here to align the beginning. Framerate is supposed to be 5fps but something in the graphics stack is not keeping up. (Also take note of the CPU usage in the bottom right corner, green.)

Video of me making this coming soon. Code: https://github.com/kleinesfilmroellchen/serenity/tree/videohax (you need to generate the images and audio yourself)
