sunset on a windowpane facing south

This photo was taken inside the observation tower at the summit of

Mount Diablo. For me what made the frame interesting was that it

involved multiple "reflections". The window is facing south; so the

sunset on the windowpane is actually a second reflection--a

reflection of the reflection in the windowpane facing east. And the

third reflection involved me reflecting upon Ikkyu's famous

lines: "mirror facing mirror/nowhere else" :-)
