I'm curious to know more info about the polarized displays, the ones with the image that will only appear when looking through a polarized filter. How many are there? I've seen Straight Jacket and Juliet/Bob (or is it a XXmetal?) that I can recall, are they the only two, or are there more? Are there different display stand setups? What's the general going rate for them? I've seen them come and go on eBay, but I haven't really tracked them. Did Oakley make anything else that plays on needing to look through their glasses to see something?
