Here are some photos a client sent in recently on the single panel glass door with two sidelites. Notice how the light is hitting the floor creating a new pattern. This pattern will move and shift throughout the day as the sun moves and changes the angle it hits the glass. Also, the pattern will be different depending on the season and how high the sun is in the sky.
