Dutch artist and designer Daan Roosegaarde has created an installation that visitors can leave their mark on: PRESENCE. This project is about humanity’s presence on Earth. It is the first solo-exhibit of Roosegaarde. Visitors can see their shadows in green and red light, trace neon light patterns across the museum floor and put their hands into thousands of glowing orbs in this museum in several rooms with interactive glow-in-the-dark concepts. The exhibition is at the Groninger Museum in the Netherlands and runs through January 12, 2020.
