The first time we walked through this house that would one day be ours, the windows in the dining room were covered by curtains. On the day we moved in we were so surprised to find this beautiful feature...and even more surprised when the sun began to dip down in the western sky that evening. As the late-day sun shown through the window, little rainbows reflected onto the walls through the prismatic bevels of the glass diamonds. You can measure the seasons by their height and the time of day they appear.
Details matter! Look around the site for other photos from the house.
