Snap - and radio receiver field strength measurement and, and...pretty
well everything has been done but with things like the Kinect it's all
getting soooo much easier but, of course, not until I retired :-( Still,
was probably more fun designing from scratch, hand soldering smt circuits,
salvaging dome switch mechanisms from 30 year old calculator keyboards to
act as in-shoe toe switches etc, etc :-)
Another idea: I would like to use my Kinect for head tracking to check

This would be eminently do-able, I think, so long as
a) the latency was low enough
b) only one listener.
c) movement was small enough to not require a major resetting of the decode
Just need to adjust the delays and levels of the speakers to compensate. If
You moved far enough for the subtended angles of the speakers to change
significantly it might be different. Don't ask me what a significant
change is, though - that would need experimentation.

PS yes, I know changing the delays on the fly would cause Doppler but so
does the listener moving - and in the opposite direction.
