Curves, angles and shapes

First day back at work. A student sent me a question about iPads and Moodle and when I opened up my iPad it was totally flat - that's a sign of how long the holiday was - lovely!
I wasn't ready to blip about work and outside it was dark and murky so in the end it was the changing rooms at the gym, located in the beautiful swimming pool building, photographed here on a much nicer day.
This blip started as a straightforward record shot but when I looked I became quite interested in the curves, angles, and shapes, sometimes reoccurring and sometimes not. I took a few shots while I was alone in my section and this was the best.
