Something to do with air conditioning?  These are not Venetian blinds – I think they are pipes!  This abstraction is taken at the closed Kodak campus in Colorado.  I wanted to title it A Quarter Past as it is indeed long since a quarter past for what was once a huge manufacturing site for photographic products.  I believe its name will live on forever. Certainly among my photographer friends who used their products for many years prior to the digital revolution!
