During his San Diego Comic Con talk with Geoff Keighley, Kojima talked about how the design for the company mascot Ludens came to be, from Yoji Shinkawa’s sketches to the final 3D model.
Originally the model was done by an outside company that is famous for character models in Japan, but Kojima wasn’t satisfied. A young modeler that was part of the team that made the movie Gamera joined Kojima Productions around that time and worked on the model. They worked on the model for about 1,5 month.
The face of Ludens is actually based on data from Kojima’s face, which was 3D scanned. Kojima asked the team to adjust the face a little bit because it was creepy seeing his own face all the time.
During the talk Kojima also showed off an impressive looking logo movie featuring Ludens, which you can check out here.
