William Stuart Systems Videograph

Interesting advert for a William Stuart Systems Videograph, a DIY visualizer kit that displays sound in colour. I have seen many of this type of circuit but not that many in colour. William Stuart Systems seem to have produced a lot of interesting peripherals for the ZX Spectrum,  if anyone has an unbuilt kit laying around or knows where I can pick one up let me know ;)

Activist Video

here is an amazing resource via the website of The Southwest Museum of Engineering,
Communications and Computation. The page is a collection of links and information relating to activist video mostly based in Chicago and other related areas of video art.

taken from the page on activist video;

"Once upon a time....

People arose wielding half inch video cameras
with pack recorders strapped to their sides...

They sought to document unpublished truths...

They created art...

They wanted us to open our eyes...

These sites below tell their story - enjoy! "

top picks include links to the video magazine Radical Software  and link to fantastic (and oft visited by me) vasulka archive. Here is the front cover of the aptly named half inch video guide the Spaghetti City Video Manual
