The challenge of designing trade show display for me is to choose the prefect images to making audience get the resonance in order to arouse their interest and impulse of purchase. I took plenty of photos in Toronto down, at campus and on the street. I took this nice photo in a small coffee shop. This cute young couple was sitting next to me. Honestly, I have to admit it is a amazing accidental coincidence because the purpose that I came to the coffee shop was just for garbing some food and taking a rest before I met those two nice people.
