Yes, I see what you mean. More specifically, try looking at
http://www.interactivelight.com/dbmenu.htm
and for MAX users
http://www.interactivelight.com/dbdown.htm
I haven't had a look at the MAX stuff yet because I'm on a text-only
terminal right now.

The web site claims that movement close to or away from, and side to side,
is detected. It's a bit ambiguous; since the thing is sort of dome-shaped,
side-to-side could be any orientation.

Is that six of one type in a single work, or six diffrent systems? How do
these things work? Is it reflection of IR (more light sensed = closer)?
The acoustic analogues of this would be systems like EMS Soundbeam, Steve
Mann's DopplerDanse and even Godfried-Willem Raes' Holosound.
(These use ultrasound.)
