I saw several of these samples at the recent stereo dinner here in
NYC.  The viewing conditions weren't that great (no lightbox, just
holding them up to the restaurant's track lighting).  In my opinion
the flower image was one of the poorer ones (for the reasons Ron
mentions), and wouldn't be what I would judge these with.  My favorite
(and the one that I think worked the best) was of several cans of Coke
(with Chinese labels) that appear to have been tossed in the air.

As with many forms of photography, it is very difficult to judge the
merits of a technique (or technology) from only one sample.  I believe
each of the samples I saw were done by different photographers, of
different subjects (the flower still life, cans of Coke for an
advertisement, a fashion/catalog shot, etc.) using different equipment
to capture the image.  Not all of the samples I saw were successful.
Without better viewing equipment I'd say the Coke shot was the most
succesful.

Personally I'm waiting for the Stereo Jet system to be ready so that I
can have prints made of some of my MF stereo honeymoon pictures.
