Via Kottke, we are given a nice lesson on the atmospheric phenomenon of ice crystal halos and the exacting collusion of conditions that must take place in order to be a privileged witness.  I am very much an enthusiast as well for the dazzling Alpine displays of reflection and refraction that are not only confined to colder and am consoled by the seeming penchant of weather formations (and have my camera ready in anticipation) to partake in the Baader-Meinhof syndrome (see also)—the frequency illusion and actually seem to manifest more often once one can name them, which feels very much the case with unusual clouds, sundogs and double-rainbows.
