There is a video behind the link that is very cool.

It is unclear to me what hardware is supported.

If you want to have kind of a similar experience right now there is wayvr btw:

This is exciting! I have wanted this since I was young and 30 years later VR monitors are finally getting here. I want to be able to switch into random positions and have my screens visible without rotation and angle issues. I have fairly severe ADHD and I move around a lot. Having this would mean I could throw my legs up the wall and still use my screen, then roll over to my belly and keep going. A phone works fairly well for this but does mess with shoulder position and is a strain, so getting something more reasonable would be awesome. Also I work with people with fairly significant mobility disabilities and I think this would be amazing for them. No dependence on where they can aim their head, just use software to correct the monitor to match their needs. Add some good inputs and it would be life changing.

What a day to be alive

Nice, having this in KDE would definitely be a great option to have besides the limited number of other ones.

A preview of the future, hopefully.
