Britglyph is “a collaborative public art project across Great Britain”.
The idea is you find a spot on the map near you, take a stone there, take a photo of yourself with that stone and submit it (the photo) to the site.
There’s a marker just near Five Ways if you want to get involved (which I think I might - it’s on my walk into town anyway).
