Fisheye plughole

It was getting late in the evening and I still didn't have a blip (I was at work during the day and at the Photographic Society in the evening).  Then I spotted my reflection in the domed cover of the pop-up waste in the bathroom wash basin.  It produces a reflection like the distorted image of  a fisheye lens, so I chose to photograph it for another fun self-portrait.

(I seem to  be producing quite a number of self-portraits recently.)
