Panorama of Chester Cathedral

I have just returned from a weekend in Chester, an old walled town dating from Roman times. The cathedral is a beautiful building, especially the tiles on the floor and the vaulted ceiling.

I took a panorama of the Strathclyde University Chamber Choir rehearsing for Evensong. To obtain the image on the left, I remapped the spherical panorama, which was in equirectangular format, to a stereographic projection.  The tiled patterns form interesting geometric shapes.
