At some point in the fall of last year (2015) Google changed their technology and it was no longer possible to embed Google Spheres in other websites.
That technology changed again in January, from what I understand, and thanks to some very smart people it is again possible to embed a sphere.
As it takes a while for my spheres to become a formal Google Maps contribution, it takes a while to embed them in a blog post – but better late than never.
Below is a sphere taken at Quarr Abbey, close to Rye on the Isle of Wight. Alex, Thomas and I enjoyed the bicycle ride there from Cowes.
