Straight or not straight?

Building: Melbourne Exhibition Centre (known locally as Jeff's Shed), Melbourne
Architect: Denton Corker Marshall

One of my ex-employer's buildings in Melbourne. The sloping sticks has created an unique experience for visitors, while they walk through the colonnade, they could feel as if the building is collapsing. The stick itself is straight but the building is not straight. LOL

*By the way, MEC is undergoing a $200 million expansion at the moment, and i was very lucky to be able to participated in the project while i was working at DCM. Thanks Ian White! =D
