Light transforms space and the human experience. In this talk, Luisa Álvarez, a light artist, will explore how urban, often inhospitable environments can be changed into interesting and welcoming places for a limited time, sometimes just a few hours, sometimes several days. For many years, Luisa has carried out ephemeral art installations, using light as an art medium in urban spaces. Her main intention is to achieve an interaction with both visitors and casual passers-by within a playful space, allowing the work to grow and evolve organically. She will highlight how the urban space can be used as an outdoor living room, where everyone can live a different experience, in this case with light. Luisa will discuss how experimentation, vindication, habitation, play and sensorial spaces all contribute to set the tone of the finished work, informing its intention and the message it seeks to convey.
