*
* This effect acts like a waveform monitor on each line.
* It was originally done by deflecting the electron beam on a monitor using
* additional electromagnets on the yoke of a b/w CRT.
* Here it is emulated digitally.
* Experimaental tapes were made with this system by Bill and
* Louise Etra and Woody and Steina Vasulka
* The line spacing can be controlled using the 1 and 2 Keys.
* The gain is controlled using the 3 and 4 keys.
* The update rate is controlled using the 0 and - keys.
