An interesting approach to 2D/3D sprites that could be interesting to look into

I just came across this Tweet https://twitter.com/KenneyNL/status/1350788503567740930 and my immediate thought was: something like this would be a great addition to Minetest to improve item wielding (and possibly other applications, such as simplified mesh creation / definition for some objects?)

It won't be an addition, you would just use that tool to make 3d models to use.
