Story behind the photograph
Here is an example of “accidental” inspiration. My daughter has left her shoes outside of the balcony door after feeding our dogs this morning. Later in the afternoon as the sun started to shine through the shutters on that side of the house the shoes suddenly were lit by the line patterned light. If you find your mind having difficulty focusing on this image for some strange reason, do not worry about it. It is not your sight. The light pattern coming through the shutters is parallel but it is not parallel to the floor, where timber flooring with its own lines runs at an angle to the light strips. This is what makes the visual tricks with our eye’s focus.
