Sheri got this solar powered spinning crystal for me for Christmas. We normally leave it in the kitchen window, but since I am stuck in the office today working on my paper, I brought it upstairs and stuck it on the office window.

It is a beautiful cloudless day, so I have fun little splashes of light shooting all over the office. Every now and then one shoots across the monitor. When I get a brain freeze, or just tired of thinking about Switzerland, I lean back and just watch the light show for a minute of two. The office faces south, so I have full sun all day long. I love it.
