Video Clock

Hello again Silencers,

I'm looking for a more elegant solution to what some of my groups performing
Cage pieces using clock time have been doing. We've just been using kitchen
timers or something similar, but it makes a little bit of a theatrical
gesture to synchronize those at the top of a piece.

Does anyone know the technical specifications of the 'video clock' that Cage
made use of in the orchestral number pieces? I vaguely remember seeing some
kind of red LED clock in a video, but could be imagining things.

Best,
Jeff
