Dancing Screens are experiments of lightweight, kinetic architectural screens that are flexible in multiple ways: in terms of materials, technology and applications. Almost as thin and light as paper, they easily move in a gentle breeze and can be used to shade, divide indoor and outdoor spaces and illuminate them at night while generating directly usable energy. For example, they can be installed on building façades or in indoor environments in the proximity of windows. Their modules are repositionable and can compose indefinitely large architectural surfaces, although they are never repetitive thanks to their continuously variable motion. Depending on the material they are constructed with, they can emit, reflect and/or refract light. They can be integrated with energy-generating components that allow buildings to harvest energy from renewable sources such as the sun and the wind in order to power people's electronic devices as well as additional light and sound effects. An exploratory prototype of Dancing Screen was exhibited in autumn 2013 in Michigan as part of the Fall In... Art and Sol festival. It is composed of six flexible photoluminescent modules with integrated solar panels. The modules resemble hybrid dancing creatures, recalling both plants and humans, that constantly move in a choreography created by the wind. Sometimes they look synchronized, sometimes they move in a canon dance. They glow in the dark with no need for electric power, while the energy harvested from the sun is directly used by passers-by who can plug their portable electronic devices in the base of the installation for a free charge. The intervention donates energy, showing the possibility of urban environments where renewable energy from off-grid installations is made available to people for free in public spaces.
