I'm not sure if there's another name for it, but "sphering" is the term I use. You take anything, and cut it, sand it and polish it until it's a perfect sphere.
For instance, my car. I'm still working on sphering my car, but it's fulfilling work.
Or dinner. It's good to have dinner that's properly sphered. It takes an extra hour or two, but it's worth it.
Also, my friends are better company when properly sphered.
Or my political opinions. I like those spherical.
