Are they crazy? This year organisers of Wellington's Performance Arcade are putting shipping containers on top of each other along the waterfront, to act as artist venues. The city's windy, and prone to tremors, and there's a shortage of containers this year, but that's where logistical thinkers like architect Alex Sawicka-Ritchie come in. Lynn Freeman talks to Alex, a key member of the team behind the free arts festival which attracts more than 40-thousand visitors a year. The Performance Arcade starts on the Wellington Waterfront this Friday.
