<BR>The odd fellow Ralph Lundsten (local old scool out of the woods kind
<BR>of fella) has a camera/TV-monitor setup which allows him to play his
<BR>synthesizers without touching anything (except a few air molecules,
<BR>but it is kind of hard to avoid doing that without boiling away).
<BR>
<BR>I think he has had this setup since the 70thies or something, so it
<BR>isn't all that advanced.</BLOCKQUOTE>

<BR>The modern equivalent of this would probably be to use a USB webcam connected to a PC..I know there are programs which watch for movement in the field of view of the camera and control things based on it..or use it as a motion sensor to trigger an alarm.
