Just figured out how to post a 360-degree render on Squarespace, and it's pretty great! Be sure to click and drag around on a computer so you can see the entire image. On a mobile device, the movement is automatic - click on the "square" icon middle-right and the views goes full-screen. It can be quite immersive!
I hope to have more of these 360 renders to share soon - they really help to tell the story of the project.
