LightWave can turn ordinary Compact Fluorescent Lamps into human proximity and temperature sensors. This requires no modification of the lamp at all and depends solely on measuring the change in charateristics of the electromagnetic noise produced by CFLs. Uses a single plug-in sensor similar to that used in ElectriSense.
This video shows a very simple example of hover gestures detected near a CFL lamp controlling a photo slideshow.
