Abstract
>>> Ensomhed på twitter <<<
Jeg har lavet et projekt der sætter fokus på ensomhed og fællesskab.
I min video forklarer jeg i korte træk hvordan det teknisk fungerer (med data der hentes ned fra Twitter).
Men konceptet er et visuelt output der simplificere den data der kommer ind og er tilgængelig for alle og til fri fortolkning.
Det er en prototype af en installation der kunne være spændende at have i byrummet og se hvordan folk reagerer og interagerer!
Jeg håber det vil inspirere dig til at tale om ensomhed med dine medstuderende.
