In related news, I'm computing a solution that looks past the TyMist. If the test rig works and is no more complicated to set up than levelling a 3D printer build plate, I might skip the TyMist and go straight to this idea.

Essentially, the Solynder is a name I recently thought up to call the helmet I've been thinking over for the past 24-48 hours. It'll vaguely be like #Tetent TestCut if the top face was a circle instead of a square. It's a cylinder for 3 reasons. 

1. I want the front door to be motorised open, I don't want any of my 180 degree horizontal field of view obstructed, and I don't want the door sticking out when open. 
   1. I remember seeing a 3D printer enclosure concept years ago but I can't find it now.
   2. The door is to keep as much of the same air in the helmet as possible. There would be air scrubbing and conditioning in the helmet, because like I'd rather eat on a washed plate instead of an unwashed one 30 restaurant customers before me ate on, I'd rather breathe some washed air and not the invisible mysteriums floating about. 
      1. At least with food, I only need to eat a couple times a day and the consumables go though some hydrochloric acid first before entering the bloodstream. Air? I think it's a direct absorption into the bloodstream and I have to breathe at least once every 10 seconds.
2. The helmet also includes over-ear audio. Looking at normal headsets, the front:back left:right head dimensions are roughly cylindrical already.
3. I want to be able to rest in bed with the helmet on. This means that the rear of the helmet has to follow a similar curve to the back of my head, or at least a continuous curve on the back of my head.

Now, as some future thinkers in the industry would be able to tell you, attempting to fit a lot of tech into something even remotely consumer-edition is somewhat far off. That's partially the reason of the helmet idea. I may look a bit closer to a futuristic Mojo Jojo than some 80's early adopter, but from my point of view, there's a lot of benefits and less of the drawbacks (and looking futuristic is probably better anyway).

Audio on the Solynder will remove the requirement from #Tetent [gd0090]. I also want to try (or at least research into) a 2 tweeter + subwoofer-ish configuration on each ear. The idea is that the tweeters are 120 degrees appart (with the main speaker inbetween them) and I could recreate 7.1 surround sound. 

Ideally, the door will be able to rotate a full 360 degrees. That means if it opened and went into the right side of the helmet, it could close from the left side and keep doing that. I think it'll look pretty cool having it slowly rotate like Thunderbird 5 whilst working.

I've used "y" instead of "i" in Solynder because I think it looks more obvious that the name was derived from "Cylinder". I guess I could go full Startup(TM) with the name with "Solyndr", a bit like "Savr" in SecondSavr.

Lastly, I'd look into wireless video methods. Having 0 cables, or just 1 when charging, sounds like a nice idea. My main lead is WiGig, but I'd take a 90Hz stream over WiFi too. WiGig supports DP 1.4, right?
