Hey, I found the Photic Sneeze Reflex site!

(By way of explanation, this is a European web site devoted to the subject of photic sneeze reflex, a very interesting topic. I'm linking to it because they use an excerpt from one of my X-Files fanfic stories to illustrate the phenomenon. The funniest part is that the character who suffers from photic sneeze reflex in my story actually gets killed in the next paragraph, although they don't include that part here.)
