Michael, Yes, polarized lenses. I didn't think much of it as polarized means to me - wearing sunglasses and getting no glare on the windshield as I drive in the early morn. But I just did a little research on the web and found this on Box Office Prophets: And then we have 3D. Apparently left for dead after the short-lived 3D craze in the 1950s, 3D films have occasionally resurfaced, usually to disappear as quickly as they came. However, two things have changed the fate of 3D: IMAX 3D, and high-profile directors taking on ambitious new 3D projects. IMAX 3D took 3D filmmaking from its ignominious red-and-green paper-glasses (known as the 'anaglyph' <http://en.wikipedia.org/wiki/Anaglyph_glasses> method) stereotype, and elevated it to incredible heights. Based on radically improved technology (polarized lenses or synchronized LCD shutters in glasses, the superior 'rolling loop' IMAX technology, and higher frame rates), IMAX 3D films produced jaw-dropping results. As more and more 3D films are released to IMAX theaters, the potential audience for high-quality theatrical 3D releases continues to grow. Some filmmakers have jumped in with both feet. James Cameron took the bathtub of money from his blockbuster hit film Titanic and poured it into pet projects. In 2003, he released Ghosts of the Abyss, an IMAX 3D film that returned to the site of the Titanic. This year, Cameron released Aliens of the Deep, an IMAX 3D film digging into undersea science and its relationship to space exploration. He is currently working on a feature film using the 3D rig developed for Aliens of the Deep. Thanksgiving Point is fun, especially decorated for the holidays. If any of you get out there to see the movie, let me know what you think. Is an ice probe possible that can cut through perhaps miles of ice on Europa? -A
