Freudenberg, Germany – Polyurethane artwork is adorning the streets of Freudenberg's old town, courtesy of Albrecht Baumer.
The old town hosts a number of outdoor events each year, such as farmers' markets and Christmas markets.
Each of these requires extra power. This is supplied by cables that have to be laid in the street. The cables are often laid over fairly long distances, and are a potential hazard to market-goers.
