virtual sidewalk

[Scot Gresham Lancaster]

Over the years I have seen and helped with tons of installations using
various technologies to realize this area of ideas. "Walk Through" a 20 year
old piece by David Behrman comes to mind. That was based around a light
source to CdS light sensitive resistors. People walking through the piece
triggered and changed setting in the patch by way of their shadows. 

Another real cheap way to get results like this is to glue piezo disks on
masonite panels that you lay along the participants path. Envelope follow
the preamped signal and use it as source to cv/midi convertor or straight
into an analog patch...
