Vintage Stereo Radio Cassette Recorder.
Transport buttons (Stop, Play, etc.) and three position switchs are in their own layers, on and off, so you can alternate them to simulate pressing action everytime a web visitor click each button.
Volume, Treble, Bass, balance, fine tune, and tuning knobs are also in separate layers. The dial hand and lit leds are isolated as well.
