To illustrate how easy it is to mistake a Class 3 Alien Threat for something completely innocuous, examine the image here. There are as many interpretations of it as there are persons analyzing it. But nine out of ten Canadian dentists who were asked to identify this said it reminded them of the pattern traced by their high-speed oral drill when they had inhaled too much nitrous oxide. In certain circles it is called "free-form invasive dentistry" (FFID). In addition, they all agreed that the streaks at lower right reminded them of the evasive action of the patient to whom the drilling action was administered. Amazingly, all described the bright area at lower left as the explosive failure of the dental lamp as it hit the floor in response to the patient's evasive action.

While these responses seem plausible, they are far from the real meaning, which is discussed in the next photo. That photo is the same scene, but enhanced. The cover story for public consumption is presented there too.
