As far as I could tell, the Corbis CD ROM that was on sale at AMNH was
   *not* the exhibition software, but rather a more general overview of
   Leonardo's work.  I saw the retail one on display and did not play
   with it, but it was based upon a central rotunda with radiating rooms
   each of which dealt with an aspect of Leonardo's work.

   I can't imagine that there would be a huge and broad marked for the
   Codex Leicester software, and it also seemed so content-y and so
   incredibly zippy that it didn't feel like any CD-ROM software I've
   ever used.  So, I suspect that it was custom for the exhibition, but I
   would be glad to be proven wrong!
