We were watching TV when Jill said, "Look there is a rainbow in you office". Sure enough when I looked through the office door, sunrays played through my crystal (upper left) to create a vivid ribbon of color and a rainbow was cast across the ceiling and on the wall. I read that it is good Feng Shui to hang a crystal in sunlit windows. This is said to be helpful in moving useful engergy into a room that has dark corners. Yes... I have searched for the pot of gold. So far, no joy. I think it is hidden in this computer somewhere.
