looking for ideas: amazing light

I've been walking around today trying to find some inspiration for my wall at the school. By the library this morning I was struck back by this amazing light effect; the strong sunlight reflected in the window glass created extra windows of light on the wall across the street (the concert hall).

The funny thing is that no one around me noticed. Some became aware of it when they saw me taking photos.

This time of the year I am always absolutely fascinated by the light and the long shadows. Could I use it for my suggestion for the school?

- did you see that Camilla has been involved in two great book projects lately?
