There was a cool device I saw once, used for timing your work. You'd program the faces for different tasks (bug fixes, new features, etc.) and whatever you worked on, you'd have that face up, and when you changed tasks, you'd turn it to something else, and it would track how you spent your time.
No, it was dodecahedral or octahedral, I can't remember. I just vaguely recall it looked like a Platonic solid. I don't remember it having a subscription. I think it just communicated with BT to your laptop or something? Might've just been a kickstarter that didn't get funding.
