thanks - glad you liked them!!
it's mostly lzx industries analog video synthesizer modules... and others, mostly DIY (syntonie, reverselandfill, fox, visual signals) that use the same paradigm - I also really like using Doepfer wavefolders - and sometimes filters - it's all electricity - but audio modules, using slower ICs (opamps etc) usually add pleasant smears
I also use an application called Lumen (only mac - windows is in the pipeline - but it has been for year) that's a virtual analog video synthesizer - which is also really handy for sending video to the video synthesizer - as it can do full screen on an external monitor - which I then feed to the video synthesizer
I've also recently got a used edirol v4 video mixer - which is really handy... adds some nice effects - and once I can find my rca splitter I can send a copy of the lumen output and mix it back in to the lzx system
for starters Lumen is a really good place to start (if you have a mac) - I started out with Processsing3, though - which is a java scripting environment for visuals - tailored to artists - and then a slightly more complicated version called PraxisLive (which is audio and video - & has some visual programming stuff in it - drag and drop components etc)
I need to fix my 12year old macbook - or get the 5 year old one back from my daughter - so I can use those as a feed into Lumen now that Syphon is no longer supported
another great way to get started is to just point a video camera at a tv (crt preferably or projection onto a screen) and plug the video camera into the same tv - so that you create a feedback loop - which is another technique I've used from time to time... and then move something - like your hand - in between them (or the tv or the camera) - then add a mixer and add in stuff from VCRs/DVDs etc

Utility modules are the dull polish that makes the shiny modules actually shine!!!
