Grumby (more off than on at the moment) has added a photo to the pool:
This was supposed to just be a practice focus shot in preparation for some water drop experiments- the first I've tried since installing a new flow restricter in the tap. I was surprised to see how smoothly the water flowed, apart from the tiny ripples at the bottom caused by back pressure as the falling water hits the pool. It almost looks like the stem of a wine glass.
