How did this work come together?

The starting point for "crt mgn" was a performance I did in Tokyo in memory of Korean-American artist Nam June Paik, who died in 2006. In the performance at the Watari Museum of Contemporary Art, I held a coil which manipulated signals from a speaker in one hand and manipulated the visual signals from a TV with a magnet in my other hand.

Isn't it dangerous to attack a television like that?
