A man walks into the Doctor's office wearing nothing but Saran Wrap around his waist.

Ananova - Japanese scientist invents 'invisibility cloak' From the oh-so-many details at the other end of the above link, it is not clear to me whether the special 'viewfinder' is part of the viewer's apparatus.. or part of the cloak's apparatus. In other words, is this what you see with the naked eye? Or does the coat work like a wearable blue-screen that the viewfinder fills in with the appropriate details when you look through it. Regardless, this reminds me of a joke I heard on the Prairie Home Companion this last weekend.
