Because it’s Friday, and because I wanted to, I’ve altered my pagespeed capture thing to also capture screenshots of each council website. this is good because over time you will be able to see if a website changes but also it means you can take all the images and play with them.
The first image is all 417 (because you don’t always get them all when you run through it) websites superimposed on each other. As expected you get a grey blob, but it does look like most sites have a box in the middle.
It might make a nice background if you’re a bit odd - every council website, tiled together in one mega-image. (see full size for the detail)
