At this time of year my bathroom window aligns itself with the sun and allows about twenty minutes of direct sunshine through a day.
It just so happened that I was showering and dwelling on reflections when the normally drab walls were illuminated with this somewhat shady reflection.
Not one to keep my camera in the bathroom (honest) a mad naked dash allowed me to snap this pic before darkness decended once more.
I even remembered to turn the shower off before jumping in with the camera.
