I believe we have found the right balance of dark material creating a bright image with good whites but the issue now to tackle is uniformity & viewing angles. I know its been stated that using a retroflective material would achieve good uniformity. I know the Dark Star does & probably all the other ones do to. The thing that sucks about using retroflective materials is the cost & screen size limitations. You simply cant find anything that exceeds 48 inches & if you do it will cost 150+. So I would really like if we could figure out a way to get the direct reflection method to work. It also has better image pop & brightness.
