@WarnerCrocker @stroughtonsmith After my VR demos -- which were sometimes more than 30 minutes at a Best Buy with Ssmsung's goggles (anyone even remember them?) -- I walked around with "VR eyes." Reality seemed different. No vertigo but fear when the VR was a flyover of Manhattan. Had to grab table to hold onto. Did spatial video have the cardboard cut-out effect of 3D movies?
