Slovakian artist Roman Ondák has an created an ephemeral exhibition titled ‘Measuring the Universe’, where he uses a marker to mark the heights of all the visitors to the space.
The art starts out as an empty room with white walls, and each visitor has their height marked on the wall. As the number of visitors increase, the wall gets increasingly marked by the various heights of all the visitors who have entered the exhibit.
His work is an in-progress visual example of the universe. A marking of one person’s height does not make a difference to a room with white walls, but when 90,000 people have their heights marked on the wall in a finite space, a black void overshadows the previously white wall.
Watch the exhibition below when it showed at Tate St Ives in 2011:
