But it's only a single piece...
...outside...
...on a park bench...
...where people sit with their backs to it! :)

Last year, Cambridge City Council announced a new initiative called "Art Benches" where artists, unable to get exhibition space in a traditional gallery, could submit their work for display in one of the custom-built benches in Christ's Lane, in the town centre. Mine was one of those selected!

 

If you're in the area, it can be seen until mid-end of May.

If you're not, then I've included a selfie of it in situ.
