Fark linked up this Mail and Gaurdian article detailing the ultimate fantasy garment made real... a cloak of invisibility.

Well, not quite, but apparently damned close. By using special tiny reflective beads, cameras, and projectors that form an image on the front of the material that mimics whatever is behind it. The concept itself has been around since at least the early 80s (I remember reading about it in Omni), but it would seem only now has technology caught up with concept.

Still a long way from making every junior high school girl's locker room unsafe, but it does prove the concept is valid.
