I'll be happy to begin - it could be fun to see other VR rooms and get inspired! I hope there's not already a similar thread (I tried to search, didn't find any)
My wife doesn't think such equipment should be placed anywhere near the living rooms, thus I'm confined to the basement. The room isn't big, but I've tested it for some months, it works nicely for VR - even though I could use more room height, height is 7.2 feet. I have about 60 ft2 floor space.
At least I got to use the sticker :-)
Two sensors on the desk - red circles (Guardian boundaries are aligned with desk edges):
Third sensor is more or less hidden on top of a tall mirror:
Got 33 ft white USB2 cable - so cables are invisible
My son playing Mage's Tale:
Having VR gives my son a lot of street credit; sometimes I wonder if his friends come over to see him or to experience VR... :-)
