• My profile picture is the low resolution 50x50 pixel animated version of this scene
• I used the default cube, inset its faces, deleted them, and used the solidify modifier on it, to create the green “scaffold” cube.
• I put a rotating animated cube inside it, with a glowing blue material.
• used sun to throw a rotating shadow on the red floor.
• rendered in cycles renderer.

To create the animated webp file: Rendered the image sequence. I got a bunch of static webp inages inside the output folder.

To create a single animated webp file from this, I used the webpmux command from libwebp:

webpmux \
-frame ./anim10001.webp +3+0+0+0-b \
-frame ./anim10002.webp +3+0+0+0-b \
-frame ./anim10003.webp +3+0+0+0-b \
…
-o output.webp

the 3 means 3 milliseconds per frame.
