Surface dial was very cool. I haven't heard much about it, though. Wouldn't surprise me to find that there may be patent clashes with this project. Most hardware is heavily patented with highly enforceable patents. It's a damn minefield.
One of the problems with "Cool UX," is that it is too "in your face."
I know of what I speak. I have designed "cool" UX elements for most of my career.
It's a mistake I keep making. I guess I like the challenge.
One of my latest efforts, is a "prize wheel" spinner for Swift (iOS/iPadOS, via UIKit)[0]. I have considered creating a SwiftUI version of it (and even started work on that), but I can't justify it.
It's really very lightweight, high Quality, and easy to use.
I keep on not using it in my projects, because it's too "attention-grabbing." There's a reason that waitstaff usually wear black.
3Dconnexion mice don't rotate, they are joysticks with twist and push/pull, just shaped like a dial rather than that on a jet fighter. Surface Dial is a scroll wheel to replicate and improve on features in Wacom drawing tablets that its host device competes with, so it's completely different.
