I have the luxury of working from home so fidgeting isn't an issue. I tend to not play with them when working as much since I end up spending most of my time picking them up off the floor. Also when you are on a phone call and hit your knuckles and blurt out an "ouch" it makes it a bit awkward lol.
If someone else didn't say it I was gonna recommend DSP. It's galactic scale Factorio in space and 3D. If Factorio automation and interstellar logistics sound fun then get this game.
For late game do e of the hardcore players take ticks per second and such into consideration so there is a sort of meta think to the game with that regard. You can still just slap automation chains together and get the job done tho. I was getting 15 fps at end game with a RTX 3060 lol.
Obosob is one of the main mods from the ergo mech sub and they are running https://lemmy.ml/c/ergomechkeyboards@lemmy.world. (I don't know crosslike communities on here yet) but that sub is picking up. There is also https://lemmy.ml/c/mechanicalkeyboards. Both are gonna be slower than what reddit was like of course but I kind of like that. I haven't seen much trackball stuff yet but right now there is a Fingerpunch board on the first page with one. I saw a Cirque build the other day too. and a hand full of sub-40% boards including one of mine!
I build custom mechanical keyboards. Got into it because of the Pandemic and now I have built 6 of them. /r/mk and /r/emk used to be some of my most visited subs on the other site. I'm now known as the goto for keyboard questions in my circles of friends.
I started getting into fidgeting more lately and took a liking to magnetic sliders and now have a few that I pretty much always have with me.
And that extended into me learning about begleri beads somehow so now I am attempting to learn that. I can do slips and 2 finger wraps and occasiaonal one finger or thumb wraps but not much else yet. I accidentally learned a stall because I messed up. I need to really learn transfers since that is one of the main things you do a lot of.
I think I am also amongst the hyperfixator group in this thread. I was previously into speedsolving Rubik's cubes and roasting coffee so I feel a lot of these answers lol.
Another movie that essentially tells the same story in a different setting is Snowpiercer. Both movies are great imo.
