Dear Deb,


While in SFO for Spring Break last week, we took our kids to the
Exploratorium. They loved it, but the thing I was most fascinated by was the
experiment entitled Persistence of Vision. It was amazing to me and I want
to learn more. Are you the scientist who developed this "snack"? If so, I
have a few questions for you. If not, would you please refer me to an
appropriate person? I very much appreciate your time, as I'm sure you get
tons of emails.
