I use https://snakeclamp.com/ - you can build a custom arm setup. I use a magsafe attachment and mount a phone running Camo on it. Works wonderfully and easy to move out of the way when it's blocking my screen.
Edit: Sorry didn't see the part about the part that projects your screen portion to the area that is occluded. That seems interesting but not sure how that would actually work...
Thanks for the links - I was actually looking for a new Camo stand and those look handy.
The idea is that the desktop would send the content of the rectangle occluded by the phone screen and the phone displays it, appropriately tweaked, tinted etc. I have no idea if it would work well enough to be useful but seems like a fun experiment.
I find myself using the Camo setup with the phone in front of the screen and I just "look around it" - I dislike the "looking into space" on calls more than the inconvenience of moving my windows a bit I guess.
