Brookfield Place has been home to some of the better public installations at the CONTACT Photography Festival over the years. The remarkable atrium, designed by Santiago Calatrava, is a great place to explore unconventional installation methods, and this year's exhibit doesn't disappoint. Alain Paiement's "Over here Over there" highlights the strange "bird's eye" perspective of his photographs by placing them on the floor of the busy corridor where people alternately pass across and peer at them. To achieve this strange vertical effect, Paiement uses what's known as axonometric projection technology, which is a 3D modelling software typically used by architects and video game designers. This one's definitely worth a look.
