This is a huge arts event running from Sept 12th to Nov 8th. Unfortunately the website is poor to say the least. I can only see information about the opening events there so far and not much else :http://www.iksv.org/bienal11/icsayfa_en.asp?cid=22&k1= footnotes&k2=events

It will feature 120 projects and 70 artists including Yuksel Arslan

If I get any more information I will let you know!
