That's looking really good. Time to give the projection optics a test run. Picture won't seem quite so bright once it's been projected to full screen size.

The screens on these are really cool. They have a pretty good viewing angle left and right, but in the vertical direction, you only get a bright picture at head height sitting on a chair (sit up straight, young man!). That's how they conserve light and get a reasonably bright picture over such a large screen from that small tube.
