Dear Jeff,

Not one of Joe Ansel's.  It was created by Bob Miller.  Many, many  
folks have looked at shiny spheres for inspiration, and many artists  
have done things with them.  You might take a look at http://www.exploratorium.edu/light_walk/ 
  and http://www.exhibitfiles.org/sun_painting for a bit more  
information about Bob, a truly amazing and wonderful person.  He died  
last November, http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2007/11/18/BA6AT9QD4.DTL&feed=rss.bayarea
