Moiré Flyscreens

MaxCo.'s flyscreens are custom-made upon receipt of a photograph of your loved one or favourite dog, and are suitable only for use in conjunction with windows or glazed doors.

Each screen (which looks like a perfectly ordinary fine mesh screen) is supplied with a matching transparent adhesive film. The film is printed with very fine lines, in a seemingly regular grid similar to the mesh itself. The adhesive film is fixed to the glass, and the mesh screen is fixed in front of it as usual.

As if by magic (yet, strangely and importantly, no magic is involved), a shimmering replica of your photograph appears, floating and shifting at an indefinite distance in front of the screen.

"Why Maxwell! How do you do that??", I hear you cry. Easy, I respond. Although the screen and film appear to show regular mesh patterns, the lines are fractionally offset in a carefully computed way. When superimposed and viewed at the correct angle, the Moiré effect creates a shimmering, shifting ghost of an image. Batteries not included.
