Gee, Bill, it would have been good if you had come up with this about ten
digests ago.  A person might suspect you were playing games to have not
posted this earlier considering how many calls there have been for evidence.  
Would you be willing to have your results inspected and analyzed by an 
unbiased committee of local photo-3d citizens?  I wonder if such a group 
could be put together...  If Bill agrees, are there any volunteers?  I
obviously shouldn't be on the committee since some might see me as biased.
