Our Sign Of Spring

Many years ago we went to a craft show and saw the above triangular glass hanging bauble with a prism inside. We had no idea that when we hung it in our front triangular window that it would be our own springtime indicator. Our home faces NNE and the sun hits it just right in spring and it radiates rainbows all over our living room.
Today is the first day of spring and sure enough there were rainbows on the wall. I couldn't get a photo of them as the flash washed them out of the photo, but our little bauble sure is accurate and has been for many years now hanging where it is.
