A mysterious gathering of characters who've found themselves stranded in a once high-end, now run-down 1930's German hotel - that's the backdrop to Heather Straka's new exhibition Isolation Hotel. It's her contribution to Christchurch's SCAPE Public Art event, where commissioned artworks take over parts of the city. The characters have been photographed against the gothic seedy set that Heather's created for the work - a set that visitors will also be able to explore and be photographed in. Heather's images have an ethereal quality to them, and Lynn Freeman asks her where they come from, and what's their purpose.
