Some of the members of my local camera club have an interesting activity.  They put a mirror (or other reflective surface) in front of a flat screen TV, put glass articles on the mirror, display a wild background on the TV and then photograph the result.  The glass objects bend and refract the TV image, creating wild and interesting displays.  Some look like the displays used by '60's band at Haight-Ashbury whereas some look like the graphed results of complex math formulas.  Like snowflakes, no two are exactly the same as the chosen composition, lens focal length, angle of viewing, etc. result in different appearances even for the same subject and background.  It's a cool take on a still life.  Here are some examples:
