Camera obscura

A man in a white shirt and black vest adjusts a white cardboard VR headset over his eyes, then looks down, while another man in a striped shirt wears a similar headset; the scene cuts to a group of people sitting outdoors on a rooftop, each wearing the cardboard VR headset, then to the interior of the headset showing a dark cityscape, and finally to the group standing on the rooftop, all wearing the headsets and looking around.
