3D Glasses that switch to 2D for people that don't want to watch the movie in 3D (1 Viewer)

Hey,
I could have sworn that I read about 3D glasses that had this option. I can't find them anymore. I think it was from Samsung or Panasonic.
I want to use them for my AE7000 Projector.
Thanks

Sharp was the company. Really cool stuff too

Thanks!

Try Panasonic TY-EW3D3MU

Another comment on the Panasonic TY-EW3D3MU glasses. The 7000 projector is one of the first to operate 3D at 480HZ picture switching rate. The glasses mentioned are designed to operate at that speed. I wonder if any of the other active glasses will run at this rate or revert to 120 or 240. This is never mentioned in the specks for the specks so to speak. (Sorry, I couldn't help it.) I can tell you that the 7000 projector with these glasses produce a 3D picture with virtually no ghosting. The only place I have even seen a hint of it is in some title lettering.
