I wonder if something like this could work for thumbnails in the terminal; I prefer to browse my filesystem from a terminal rather than the point and click file manager typically, and it would be really useful if I could have a grid-style `ls` with terminal based renders of the 3d models (thinking STL/STEP, 3D printing) in that directory. Bonus points if I could preview/rotate the model to inspect it.

eza [1] is a step in that direction. It lacks the interactivity, however.

You can do this with thumbnails using sixels already
