arduino based SONAR
I remember coming across an arduino based project that would seem to fit the bill nicely but can't for the life of me remember the search phrasing that it came up through but it went basically like this:
# Mobile unit sends out an ultrasonic ping
# arduino with three (or four) receivers around 'pitch' takes the differential timings of the signal to each receiver
# arduino calculates the location of mobile unit from the differential timings and locations of receivers
# arduin transmits coordinates back to mobile unit via Xbee
This method only requires accurate measurement of the locations of the receivers, not too difficult, I remember it saying they managed accuracy in the 10s of centimetres. Not too shabby!
Please keep up, boffins have already managed to create living cells able to produce laser light, its just a matter of time before we have sharks shooting laser beams out of their frikkin eyes! :-)

Did I fire six titles or only five?
An interesting but rather basic review, if you're suggesting these are okay for gaming how do they compare to other multi channel headphones around, such as the Razer Barracuda? Just because in B:BC2 the water sounded watery and firefights intense, a good pair of 3D headphones should allow you to pinpoint the location of sounds 360° around you quickly for that 'He must be cheating!' response!
Based on this sparse review there is no way I'd go and risk my valuable beer tokens on these, surely you must have someone on the El Reg FPS-frag-fest desk willing to conduct an exhaustive review?
Title? I don't need no stinking title!
My vote for the quote of the day to Lawz for

The farce is strong with this one...
