Reflections

After a stupidly long cold run we noticed this reflection on the wall upstairs (I thought I'd help you all out be pointing at it...). Though I live in this house I can't quite work out what the sun was actually reflecting off and if I had any energy after running 16 miles I'd get off the sofa, peer up the stairs and check but I'm not going too mainly because it's dark and the sun is somewhere over Australia by now (I have a Geography degree don't you know...)
