Here is a behind-the-scenes look at the making of the artwork for East Point Park Bird Sanctuary Pavilion in Toronto. The structure’s weathering steel walls will be perforated with the english and scientific names of migratory birds that have been sighted in the park, with a cloud of sparrow silhouettes in formation flying overhead. 3D modelling and laser cutting was used through the design process to quickly prototype at a one-to-one scale, helping to fine tune the some 4,000 flying fowl that make up the work. Site work is now underway so stay tuned for more photos as it develops over the course of the summer.
