Ha! Definitely not stealthy, but interesting, nonetheless. I'm still having trouble grasping how it actually works...
Oh. OK - It looks like the cylindrical thing is actually a camera (sold separately) but I cant tell if the clamp/holder is a part of the camera or removable. If you could buy that holder it might work great for holding a mic (although you'd probably look pretty ridiculous with a condenser mic on either side of your head!) Maybe for a Halloween show
