Years ago, I read about a hat that some Hollywood stars had found useful for fighting paparazzi.  Mind you, I don&#x27;t recall the source, and it my have been tabloid nonsense.<p>The hat had a circle of IR LEDs (or something of the sort) emitting 360 degrees of invisible-to-the-naked-eye light.  Photos of anyone wearing the hat had a similar effect to using a flash in a mirror, the subject was completely washed out by light.<p>Again, I&#x27;m not sure if this was bogus or not, but it seems the demand for such a product is only going to become greater.  Hell, I&#x27;d buy one.<p>Does anyone with expertise in this area know if this type of device is technically possible?  I&#x27;m voting no, otherwise we&#x27;d be seeing these devices everywhere, and there would be laws against wearing them.
