reading some of the comments i was expecting something really high end and polished, but yeah, this is something you could with a headset 1/10th the cost
I was expecting an app that works like the VR version of a laser indoor measuring tool. Where you hold a piece of wooden board and the VR tells you where it should go and then another person wearing a VR helmet attaches it to a post, also at sub-mm precision. Etc.
