I just saw Beowulf with these new 3D glasses with clear lenses instead of the usual red and blue ones. They worked better than any 3D movie I have ever seen before, and my eyes didn't hurt afterward and I didn't have a headache. I want to use them to watch something else, but it seems that every video on YouTube uses the old red and blue graphics. Does anyone know any websites that might have videos that can be watched with clear lensed 3D glasses?
