The Delegation building stretches out beyond the atrium, featuring conference rooms, a resource library, and office space, as well as private quarters for the Aga Khan when he's in Canada. While the Aga Khan is not strictly speaking a statesman, he has extensive contacts with heads of government. This courtyard garden is another element of the design of the property; it's well cared for and quite peaceful.
Taken from a walkway above the central atrium, this gives a closeup of one of the screens hanging from above.
Close by is the only artistic display on the premises. This is a headpiece by First Nations artist Bill Reid, one of the same figures incorporated into his Spirit Of Haida Gwaii.
By the way, a quick note to those I follow on Facebook. That site seems to find it hilarious to suspend me for a month for a comment that didn`t violate their code of conduct, while letting white supremacists, bigots, and people committing slander get away with saying whatever they want. Needless to say, I'm not impressed with Zuckerberg and his precious social networking site at the moment.
