The Mobile Hedges (2011) was a public space urban art intervention, designed to create temporary spaces for people to hang out and socialize on the famous city square designed by Oscar Niemeyer and located between the National Art Gallery and the National library in Brasilia, Brazil. The 2 x 2-meter hedge modules on wheels were pushed around on the square to create shade from the sun and to make human-scale intimate spaces in which to relax, enjoy the company of others, to take a snack or just rest. The Mobile Hedges art intervention aimed at making the ‘life between buildings’ a more liveable space for people, to reference influential Danish architect Jan Gehl’s book title: Life Between Buildings (1971); and acted at the same time as a criticism to Oscar Niemeyer’s lack of consideration for people in his public architecture while at the same time introducing a solution, however temporary and experimental.

Another sculptural work with hedges is titled: As You Walk Closer ‒ Hedge Grows Taller. It is an interactive public sculpture, installed for five months in the city of Køge, Denmark, for an exhibition with KOES ‒ Museum for Art in Public Spaces ‒ in 2013. As you sat on the bench to enjoy the view over the sea, you activated a sensor in the hedge and it grew out of the ground, blocking the view.
Hedges are placed around most people’s land to mark their property and create privacy. In Denmark this kind of hedge has become a symbol of fear for what is foreign and unknown (e.g. other immigrating cultures), and many people hide behind their hedge in their private cozy garden sometimes not even speaking to the neighbors on the other side of the hedge.

Another interactive hedge work includes Nervous Hedge, which was installed in front of the main entrance to the art museum in Køge, Denmark. The subtle shaking of the hedge triggered by a motion sensor suggested a new and surprising behavior of the hedge.
The hedge is a kind of wall, nicer than a grey concrete wall or wire fence, a green living plant but still dividing space like a natural living wall. The hedge as we know it is static since it does not move, so by creating interactive moving hedges in the public space people can create new possibilities by changing the public space, transforming the idea of the hedge as a static wall, and further making the public space a playful and fun place in which to be.
