Those three presentations were interesting.
Jaime Lerner talked about city planning by showing quick drawing, which helps views understand quickly. I liked, especially, turtle one. He also explain cars, as if they are human, which is very interesting way.
Vik Muniz presented his work. In the intro, he captured audience attention by changing his mood from awkward to funny and informal conversation way. Showing his works by using photographs and videos with narrative explain leads audience to focus on his work.
Doris Sung Kim explained her personal experience, which is related with her presentation, at begin part. This make views feel comfortable for me to listen to her. Showing specific image helped me to understand her presentation clear.
