That's a great idea! I don't like how the clip eats up display at the top - it should be possible to have this more compact, like e.g. Logitech's top of monitor mounts.

Would be nice if they had a hinge on it so that it could swivel 90 degrees out of sight when not in use.

I'm achieving largely the same with my flex mount solution, although I do have to have it to the left a bit due to my middle top monitor. I have a lot more of the monitor obscured though, but it's not that bad.

When e.g. Samsung perfects their under display cameras, we can hope for built in behind pixel cameras in regular monitors. Give it a few years!
