And a much deeper viewer.
Replace a matte projection screen with a "super beaded" perfectly retroreflecting screen (effectively a condenser/field lens setup) and the image brightness/angular size would not depend on
distance from a viewer "coincident" with the projector (but that's the only place you'll see the image).  The benefit (?) might be a that using a bigger ("MF") screen area means more
"beads"/steradian = finer grain.
