I was in a meeting at D....y I..........G (signed an NDA) today and on the phone with Cyro about custom colored acrylic sheet. The minimum run for cast is app. 2000 pounds. The minimum run for extruded is app. 15000 pounds. So if anyone is thinking about custom colors, make sure your wallet is nice and fat.
At another location, I also saw something that amazed me. A white film, that when projected onto, flips the image when seen from the backside. So text is right reading on both sides. The film is probably only .005" thick. I'm guessing the projector projects 2 images at different wavelengths and the front picks up one and the back picks up the other. If anyone has another idea how it works, I'd be interested to know.
That's it.
Cheers,
Doug
