the sparklies are a known side effect. they are in the process of reducing it. they even have a way of measuring it. i cannot recall the name they had for it. it may have been spackle.
apparently they managed to reduce it at the show by 3% they expect it to still drop in half from where it is.
the machine there was only about 1500 lumens. they were not even in a blacked out environment. so no conclusions could be drawn on contrast.
they expect the next light engine model to be ready in a month or so which will take them to 5K lumens. next year up to about 10k.
their active 3d was spectacular. one could almost say too good. as you would expect, the level of detail was fantastic. they had an animated sequence going through an Egyptian temple and an IMAX trailer that was great.
Apparently they have already been used in Home theatres.
if that had been in a blacked out environment... it would have been a must see.
however in the 3-D realm, Da-Lite had a new material 3D Virtual Greyhttp://www.da-lite.com/whats_hot/index.php?wID=176
And it was in a tent they had off booth. it was pretty good, your standard passive 3-d demo... THEN... they showed an operation! at least the view from 3D cameras inside the body where the remote stuff was cutting and chopping and cauterizing... it was friggin awesome. great display.
