I recently designed a timeline for a book titled Space For Urban Alternatives? Christiania 1971-2011 (Thörn, Wasshede & Nilson eds.), published by Gidlunds for the 40th anniversary of the Christiania community in Copenhagen. It was quite tricky but solved in the end by an incremented scale, with the units starting at 100 years and ending at 10 years. There will be a launch and seminars at Galopperiet – Stadens Museum for Kunst on Sep 24 11am-4pm. Copies will be available there, but the book as whole is also available as a free download.
