Video Synths, DIY VJing, etc.

I've been scrounging the net for "Video Synths" and older analog visualization devices with schematics and have come up completely empty handed.

I know that software is all the rage, but I'm looking for a DIY hands-on modular type device, to run alongside my audio analog modular. Lot's of great sounding machines but no clues how to make one...

Why not just get an old oscilloscope? You can see the waveforms of the music, or use the X-Y mode to create lissajous patterns and such. Put your left channel on X and your right on Y, instant video show. Or is that not what you had in mind?

In the days before software could do any video processing, there were some hardware video synths. They can be found used, but are still expensive:
chromascope

fairlight CVI

Lots more info on video synthesizers here:

A new video synthesizer (expensive):
Roland CG-8

In general, you can do a lot more with modular video software, here are two free programs:

Also Jitter and Visual Jockey are popular (but not free).

Thanks egw for replying, and great site you have btw.

Some of your links are defunct, some lead to exactly what I'm looking for minus the schematics, and others lead to software equivalents which are what I was hoping to avoid.

I pretty much want to take original and found footage, sequence it to music and add effects/anomalies via a hands-on interface. My mind doesn't lend well creatively to software but I guess that's what I'm left with, eh?
