"As Autumn Leaves" (AAL) is a spatial installation designed and built by students of the Laboratory for Computational Design (LCD) for Beijing's 2013 Design Week. Located in a historic hutong district in Beijing, AAL highlights the existing entrance to Dashilar Factory where emerging creatives exhibit their design. The concept is based on ephermerality of nature. As temperatures change, autumn turns to winter, and trees shed their leaves, AAL recalls the passage of time through changing seasons.
