iz3d has been offering something similar for years. I tried it out at microcenter, and it looked like complete, utter, unbridled ass. The gimmicky 3d look and glitching HUDs/crosshairs are so not worth the price of admission. ($250 being the price of an average 22" TN LCD these days? Really? Do they do all their shopping at e-stores with 2007 prices?)
At least with the 120hz active shutter version you get a fast monitor after the "wow" factor wears off in a day or two.
