Gamasutra has an interesting article up which (while only tangentially related to Dragon Ball) you may find of interest. Titled “Pecha-Kucha and Game Culture in Tokyo“, it is a brief recap and explanation of Pecha-Kucha, a presentation format where the individual or group has twenty slides and twenty seconds for each, totaling six-minutes-forty-seconds. In this particular event:
… Patrick W. Galbraith, author of the Otaku Encyclopedia, gives a presentation about Japanese anime, game, and geek culture.
Two hours in: the audience is getting restless. Presentations have been going on for a while now, but when Galbraith, a PhD candidate at Tokyo University, is called on stage, people take notice. He is, after all, dressed like Goku, a character from the popular manga Dragon Ball. Accompanying him is a girl dressed as a French maid, Ayakawa Yunmao. She is head of the Maid Cooperative, a professional organization for the hundreds of maids who work in Tokyo’s geek Mecca, Akihabara.
These women work at maid cafes where customers come to relax, hang out, and occasionally pay for a maid to accompany them while they shop for video games and comic books. Together, they teach the audience about Japanese Otaku (geeks) and Akihabara. This isn’t Galbraith’s first time presenting. He says he always receives feedback from his Pecha-Kucha presentations. “I use a lot of props. Give ’em the old razzle dazzle.” People respond to that.
