[sci.virtual-worlds] water levels with LED's

recently on BEYOND 2000 (everyone's favorite tech show... yeah right)
I think the date was 12.8.90, they had a spot on a new digital level that used
the old waterbubble in the tube trick but with a new trick.  LED's were added
so that they would shine through the liquid and detectors on the other side
would tell where the bubble was.  It is supposed to be VERY accurate.

Pretty darn useful if you ask me (nice clean way to measure head tilt). The only
problem is that I have no idea where I could get ahold of these little beauties.

any thoughts?

David
