A few hours before the end of the Light challenge I decided to experiment with cross polarization. I shot a few dozen pictures of different items and ended up using
Although it wasn't my favorite, I figured it would fare the best score.
Had there been more transparent plastic it would have been more colorful, as with
My favorite (being the most fun) was  , simply because I was able to take an ordinary mundane object and make it appear very different. (some will still think it to be mundane and ordinary :p )
There is something that surprised me while taking these that I'm hoping someone can explain. The setup was a makeshift light table, using tungsten lighting diffused with white plastic. On the plastic I placed a 12x12 sheet of polarized film, and laid the items to be photographed on top of the film.
Next my question. I tried using 2 different polarizing filters. The first a Tiffen linear polarized filter, the second a Tamron circular polarized filter. The linear filter should have worked the best, but yet results were much better with the circular. I've checked and rechecked the model numbers on the filters to make sure someone didn't accidently switch them in their boxes. Any ideas on why the circular would work better? Could it be the Tiffen is very low quality?
Also there are a number of things you can do with cross polarization. I would be interested to hear how others have used it.

Personally, I'd have scored the "ziploc" pic higher than the one you entered. It has a much more "human" touch to it.
I'm not sure about the polarizing issue, but I suspect it has to do with the fact that you used a point source very close to the object for light, so the light was radiating in a circular pattern through the diffuser. Sunlight is composed of parallel rays because the source is so far away...
