We covered this window in our shop with our Window Perf vinyl. From the outside, it’s a cat. From the inside, you see outside clearly. This is done by perforating the vinyl with thousands of 1mm size holes. The Window Perf material is black on the adhesive side, and white on the print side.

We see Window Perf being used, for instance, on bus windows where they want to put graphics on the bus but let the passengers see out. It also has a following in retail stores where they don’t want the public to see the inside of the store. Often they want to hide the view of the checkout area, but let the checkout clerks see what’s happening outside the store.
