The while line is That's One Tall Fucking Thing aka the Beanstalk by Mike Light, David Rattray, and Wil Van Hazel. It's a dynamic light sculpture made of a long line of blinking christmas lights hanging from a very high helium balloon. Check my other photos of the Beanstalk.
In the back (in the middle), the Connexus cathedral.
See the ladder to the platform i'm on.
