Iwata Asks: Miiverse Penis Drawing Detection Took Weeks to Develop

Kurisu: So the team and I had to come up with a way to create a system that auto-detects those types of pictures.

Kato: Kurisu-san suggested we study different types of penises in order to create figure out the relative shape and size people would draw. We spent a week doing that before we realized that we should have been looking at drawings of penises rather than real-life pictures. (laughs) We were very embarrassed about that.
