Nickel ;-) It is working very well with 2 projection design projectors and 2 linear polarisation filters... But it is quite hard to configure correctly the projectors alignment and the special screen is fragile. Of course the price is also quite prohibitive. As far as I've experiment, it is much more comfortable to use a DepthQ projector. The glasses are more expensive and more heavy to wear, but the config is simplistic and the results are good.
