# Efeu Ex

Ivy Ex consists of nature and a pneumatic machine on the house facade of the Stadtwerkstatt. The installation machine is pneumatically driven via four ratchet wheels, a spring is transported between plant circles via approximately 15 deflection rollers. The façade installation is very similar to the Stadtwerkstatt-Infolab. In other words, the installation makes the artistic content of the Stadtwerkstatt visible as references to nature, information and technology are made.

A text about the facade installation Ivy Ex has been published in the Versorgerin #105.
