Yes, the Redscape Audio was very interesting and very cool indeed!
I'm not surprised that there isn't much info yet, as I believe they indicated that it wasn't released as of yet, but would be very soon. They were thinking it would be around $200 or so for the software and the hardware, but that could change. The hardware is just this little plastic box that straps to the headband of any headphone and then uses a long USB cord to run along the headphone cable and into the computer. As of right now it is Windows only, but they are hoping to have a Mac version soon too. The little plastic box contains various instruments, like a compass and gyroscope, etc. in order to relay real-time tracking information back to the computer and the software. Thus, anyway you move your head, once you have centered using the software, will change/affect the sound to that direction.
It is really cool and seemed to work really well. I tried it out on an action movie they had going, and switching back to "normal" mode really showed how fun it was with movies, everything was just 2D after turning it off. I also tried it out on their music setup and it was really cool there too, but probably more of genre specific thing or by album for me. It really opens up the sound and didn't seem to degrade it at all either, but I think I may prefer it more on live recordings compared to studio albums in general, but if I had a studio album that I wish was live, it would work really well here too. At least it gives you options and you can toggle it on and off as you wish.
Also, in my short time with it, I preferred the tracking with the movie more than with the music. Not that it was bad with music or anything, but just made more sense to me with the movie, as you are watching a screen in a certain direction, etc. With music, it would be cool with some classical stuff and others that have a big stage presence, as you could center and then hear the different sections as sort of a crazy 3D imaging environment, that might put you more into the music hall than other solutions.
Audeze also has something similar, but I really like that you can use any headphone you wish to with this solution.
As a side note, the owner used the EQ options in the software to really tame the HD800s, so it's a pretty cool all in one solution if you already apply a little EQ using similar software.
Hope that helps, but let me know if you have other questions, I might be able to help answer them since I did demo it, but I am no expert in the product unfortunately.
EDIT: Thought I'd throw in a quick funny story about these from the show I just remembered. The owner and I had a bit of a chuckle because of how crazy cool the technology of the tracker is and he wasn't exactly sure how the tracking would respond at certain points during something such as an airplane flight. After that I couldn't help it, just imagined falling asleep with tracking turned on, flying over the Bermuda Triangle, and then waking up suddenly to a carousel of insanity as the internal stability of tracker goes on the fritz! Would be pretty funny, who knows, maybe even a bit scary! Anyway, very cool technology and I also signed-up for their mailing list at the show, which is probably the best way to currently get new information about these for those who are interested.
