Overhead Projector as a Musical Instrument

(YouTube Link)

Blair Neal turned an overhead projector into a musical instrument. As he scrolls the transparency, a camera reads the placement and color of marks as musical notes. The project is called "Color a Sound."

That's a cool concept.

I've been to a lot of electroacoustic concerts in my day. And one thing about electronic composers is that they're heavy on engineering, and low on musical training. They might come up with genius ideas, but the application is just not musical.

Such is the case here. It's pretty, because the filter is set to a major scale. In the hands of a composer, something interesting might very well come out of it, but otherwise, it's just random nonsense on a page. But very cool idea, anyhow. I'd like to see improvements that include dynamics and the ability to have crescendos and diminuendos. That would be rad.
