Outdoor campaign a la We're Not Really Strangers but in Danish – would have a huge impact to do posters that just said
"Jeg er fucking stolt af dig"
"JEG ER BANGE FOR AT SKUFFE MIG SELV"
"Det er ikke din opgave at fikse den person der ødelagde dig"
Prerecorded guided meditations like the Ditte Ejlerskov Exhibit or even just performed live on the spot using a massive plane of diffused light that can change colour. Cloud space?
