Kawasumi-Sensei, a sushi chef who teaches at Tokyo University, wanted to honor Barack Obama. Since he’s a sushi chef, he decided to do so in sushi. After much trial and error, he came up with a result he was proud of, complete with ears.
Brown rice is used for the skin, black sesame seeds for the hair, tiny shrimp for the lips, and fish paste for that winning smile.
The Obama sushi is at about marker 1:27 in the video above.
