Welcome to the digital edition of mondo*arc #80. A giant heliostat reaches out from the cover of this issue. A technology usually found focusing the suns rays at solar power plants, this example juts from the side of the new One Central Park building in Sydney, part of a regeneration of the city’s CBD. Here however, instead of directing daylight to a single point, light is redistributed to street level. And at night the entire structure becomes the canvas for Yann Kersalé’s Sea Mirror installation – an allegorical link between the city and the sea.
