I think is not the physical distance who matters. It is about really doing and thinking something else in that precise moment. I suggest you watching an action movie with headphones on, light out, i-phone shut down. Or a comedy. Or listen to a music (headphones on) and reading a novel. Or even better make love while they all parade nationally.
By doing this and ignoring the planetary event you will put the maximum distance between you and “the event” and don’t it occupy your life.
About how to show lovemaking in the gallery, you just can have an audio….either just voices of the couple making love or if you want to be more ironic voices of the couple making love and in the back barely heard a tv with the live coverage of the opening..
