It was a little bit disappointing to realise that it was just caused by light reflecting from the curved surface of our shiny bin (trashcan). I had hoped for fairies or some other kind of special, magical reason.
However, the effect only lasted for about five minutes - while the sun was in exactly the right position to shine through the hall window and all the way into the kitchen. I suspect that this is only a late autumn/early spring thing too - related to the sun being very low in the sky.
So maybe it was a tiny bit magical after all?
