Holophonics, not a new technique, but an exciting one imo. Used by artists like Pearl Jam and Pink Floyd.
Ok, get your headphones on!

Some history (from wiki ofcourse):
Holophonics rose to fame in 1983 with the release of a recording entitled Zuccarelli Holophonics (The Matchbox Shaker) released in the UK by CBS which consisted entirely of short recordings of sound effects designed to show off the system. These included the shaking matchbox, haircut & blower, bees, balloon, plastic bag, birds, airplanes, fireworks, thunder, racing cars. This specific system was designed and promoted by Argentine Hugo Zuccarelli, though the technique of binaural recording has been around for over 100 years.
Zuccarelli came up with a theory that claimed that our ear is a sound emitter, producing a reference sound that combines with incoming sound to form an interference pattern inside the ear. The nature of this pattern is sensitive to the direction of the incoming sound. Our ear's cochlea detects and analyzes this pattern as if it were an acoustic hologram. The brain then interprets this data and infers the direction of the sound. This was printed in the magazine New Scientist and was followed by two letters casting doubt on Zuccarelli's theory and his scientific abilities.[1][2]
It is unclear whether Zuccarelli himself believed his own explanations or whether they were simply used as marketing hype, intended to distance his product from other common binaural recordings.
Like all binaural recording, Holophonics simply reproduces the interaural differences (arrival time and amplitude between the ears), as well as rudimentary HRTF (head-related transfer functions). This causes the auditory system to hear the illusion of sounds existing from specific directions. Well known limitations of the technique include unreliable effects for some listeners, as well as very poor frontal localization (everything sounds like it's coming from behind the listener, explaining the narrow choice of demonstrations) [citation needed].
The Zuccarelli Holophonic recording technique can validate the front - back localisation capabilities of a binaural recording, where the listener can distinguish the sound of a matchbox behind their head from 2 sound sources. To produce digital holophonic binaural recordings, a mono source requires many HRTF channels combined.
The basilar membrane analyses many individual spectral components of a sonic environment, all processed in parallel by the brain
The digital process for generating holophonic sound can be computed from just a few lines of computer code.

Apparently you can make recordings like this if you build a couple of electret mics into the "ears" of a cheap styrofoam wig stand. I bet you can further the experience by modeling outer ears for it, too.

I'd seen somewhere (years ago) a microphone for this type of recording that look just like ordinary headphones. a headset with mics instead of earphones
which is cool, since you wouldn't look as dorky or obvious as someone carrying around a regular stereo mic, or a styrofoam head.

and back when I first heard of this technique, I'd heard some audio that puts you sitting in a chair in a room with a wooden floor, while a dominatrix walks around you in heels.
this was a long time ago, when people still used to say things like "virtual reality" and such.

I think you can do this with a set of $99 binaural microphones and a minidisc recorder.. that's what I did...
