As far as Laserium on a flat screen is concerned - It hasn't ever really worked. We've done it, but not for a really long run. Now perhaps it's because we didn't know how to market it on a flat screen for a long run. I'm willing to consider that possibility. But I'm not aware of it ever being done on an IMAX (flat) screen. Laserium has been - since before the beginning - intended as an immersive experience. It looks good on a flat screen, but there's something special about the dome experience. As Dan Neafus at the Gates Planetarium pointed out "the frame" in a dome is the horizon. It's a different experience. My goal is to lift the audience up into the stars. That's why I hate beam work and anything else that pulls the audience back down into their seats.
