Here is my interpretation for the day matching the current screen saver that Microsoft 10 has given me:

They remembered Paris, and terrorists attacked the Republicans' political rally. The candidate who was addressing the public at that time was shot. His microphone dropped to the ground. He was rushed to hospital but he never came back. The variety of footprints indicate that men of different types were gathered there, but had no real unity. The varied orientations of the footprints also illustrate chaos and a lack of direction.

Are the employees of Microsoft psychic? Are their screen savers precognitive images?

It's quite interesting to interpret these screen savers. It's so much like interpreting other people's dreams!

Maybe I should start a compilation of all of them.
