    WOW! Good job on the project and the tutorial. Now you need to learn about safe practices! Open wires with line voltage, (220VAC no less!!!), hot lamp directly on cloth?? Also, a warning about the ENORMOUS jump in volume when the music starts would be welcome.

    So what is new or newsworthy, the first time I did that was in 1966.

    You're ahead of me. I didn't do that until 1980:D
