This is a structure I saw at Pearson International Airport in Toronto, Canada. While waiting for a flight to Beijing, I noticed this extraordinarily huge structure. I didn't touch it but it looked like it was made out of a plastic but it looked very heavy and strong. When a person walks out from the security checks into the gate, they would hear their own footsteps. The whole structure produced an echo when sound is emitted inside it. Many tourists and children made sounds to test it out.

The form of the structure is basically 4 curved walls that leaned inward. All the lines are very curved and they are geometric shaped. The hue is black with a high value. The opacity of the actual walls didn't let any type of light through.
