First i see an utterly ugly carpet my eyes have to adapt to 😜 then i see 15 lenses or 16 if the case on the left is one also. On the other pic i see two tandems for the 2 screens in the back, so 4 Projectors, i guess the cases are empty already.

awayvery good, there are 4 stacks & screens total! & this Red Rock carpet is ugly indeed

I guess there are 17 lenses and 2 projectors.

8 projectors & 16 lenses
