I was recently mentioned in a tweet by Paula Rodríguez who has reworked the images I pulled from Google's Tea House themes into a single wallpaper. She's done a wonderful job of combining all the different exploits of our little fox friend and I encourage you to check out her art.
Seeing Paula's work reminded me that I had always wanted to produce a dynamic version of the Tea House wallpaper that changes throughout the course of the day. Since this is now natively supported in macOS, I set about creating one: I found and fixed a number of bugs in the original HTML, added a script to auto-generate frames for different resolutions by scripting Chrome, and then used Equinox to generate the dynamic wallpapers.
I've packaged up a few different sizes of the dynamic wallpaper for download directly here. If there's a specific size you'd like, please feel free to reach out, or generate your own from the source on GitHub.
In the process of updating the wallpaper I realised Google have themselves updated the theme and, while they haven't added support for retina screens, they've adjusted the colours and gradients--perhaps something I'll pick up in a future update.
