Cave lights

Daan Roosegaarde's latest interactive installation, "Lotus Dome" used human movement to light up a cave in Jerusalem.

Daan Roosegaarde has elaborated on and expanded his design practice of “techno-poetry” to illuminate the rustic interior of a cave in Jerusalem.

Dutch interactive and social designer Roosegaarde has continued his exploration into merging innovation and imagination, otherwise known as “techno-poetry”, with his “Lotus Dome” interactive installation.

The motion-and-body-sensitive dome uses hundreds of “smart flowers” composed into a large-scale sphere to light up the cave. Interactive software senses the body movements of visitors and sends signals to light up multiple LED lights.

The installation creates beautiful patterns through contrasting shadow and light against the textured interior of the Zedekiah Cave in Jerusalem, a five-city-wide limestone quarry within the old city.

"Lotus Dome" illuminates flower patterns as it responds to human movement, and transforms the 20 000-square-metre cave into an area that investigates human behaviour within a network of carved voids.
