Is it a space probe from Star Wars? Or some new robot? Maybe a shaker? Nope, it the Holophone H3-D microphone, a 5.1 multi-channel surround sound microphone. This is described as 'economical' as it will be priced at $1,695. Their H2-D Pro microphone costs $5,500.
What's it do? Well it outputs multiple channels, and provides a surround sound image. You need the ability to record all those channels at once separately (a drag if you only has a USB interface or a low-cost recorder.) What's it's application? Ummm...well I'm sure it has some application for live recording, though novice that I am, I can't help but think that you have a lot more control if you mic things separately.
The astute amongst you will notice that this image is a 3D model. Their microphones do exist though; at least they have pictures of their H2-D on their website.
