Wicked DIY analog video synth

Brian McKenna has hacked up a very cool 'signal bending' analog video synthesizer. It's kinda like circuit bending, except it works by overlaying audio waveforms onto the VGA output of a computer. The result is an unpredictable and quirky video glitch machine.

"Video synthesis tends to be dominated by digital technology these days. However, analogue video synthesis techniques can still offer a great many advantages in terms of aesthetics, performance, simplicity, and adaptability. Not to mention the non-linear surprises which can come from working in the analogue domain. This "VGA Expropriator" will be the first in a series of proprietary analogue hardware devices which seek to explore the possibilities of digital/analogue hybrid technology in video/audio performance and studio production contexts. The first offering here is essentially a new design with it's creative process making ample use of circuit-bending methodologies."
