Here's some more information from the organisers:

The second Istanbul Design Biennial The Future Is Not What It Used To Be organised by the Istanbul Foundation for Culture and Arts (İKSV) and curated by Zoë Ryan opens to the public on 1 November. Throughout the city and in the biennial hub, Galata Greek Primary School, the biennial features 53 projects from designers all over the world that ask: "What is the future now?" as well as panels, conversations, workshops, film screenings and many other events until 14 December 2014.

By rethinking the manifesto as a platform to frame pertinent questions, the projects question the role of design, its relationship to society, and its ability to be an active agent for change. The second Istanbul Design Biennial is co-sponsored by Arçelik, Doğuş Group & Bilgili Holding, ENKA Foundation and VitrA and it is held free of charge.

The biennial was launched with a media conference held on Thursday 30 October at Galata Greek Primary School with the participation of İKSV General Manager Görgün Taner, Director of Istanbul Design Biennial Deniz Ova and curator Ryan.

Ryan says Istanbul has a thriving creative community, so it seems an especially appropriate city in which to reflect on the field of design. In an effort to contribute to an already rich dialogue in Turkey and focus on issues urgently affecting daily life, the biennial brings together diverse design ideas from across the world for an emerging set of conditions.

"The 2014 Istanbul Design Biennial is envisioned as a conversation starter, Ryan said. "It is an occasion to present a range of projects by some of the most inventive practitioners working today, and emphasise the critical role that design plays in identifying points of urgency and posing questions about the objects, buildings, and environments we interact with daily, as well as materialising outcomes."

The conference was followed by the exhibition tour guided by Ryan and associate curator Meredith Carruthers. After the tour, The second Istanbul Design Biennial Academy Programme Exhibitions and other events were visited at the biennial's event space, Antrepo 7.
