idea. Action Drive was eventually cancelled. While working on other projects, Takahashi continued to try to think of game ideas, seeking to grow beyond being just an artist for Namco. Takahashi cited two concepts that led to the inspiration of Katamari Damacy. The first was a prototype shown by Sony Computer Entertainment called Densen (Japanese for "power line") that had the player as a young girl traverse floating islands of various homes connected by power lines. The game, though never released, gave Takahashi the idea that the ordinary world could be made interesting with only small changes to perception, and that a game could be fun without the need to cause violence. The second idea was from the game of tamakorogashi played in Japanese school's undōkai or sports days. In tamakorogashi, students attempt to push a giant ball into a goal. Both those ideas led to him thinking of a game where spinning a ball would roll ordinary stuff into it, making the ball larger and larger over time. The evening he conceived of this idea, he spoke to a friend, one of the game designers in Namco, to see if it made for a good game idea, who agreed it had potential. The next day, he spoke to his former boss, Mitsutoshi Ozaki, about the concept, further adding a way to reuse the King and Prince characters he had previously proposed, who also agreed it would make for a great game. However, as Takahashi was in Namco's art department and not in game design, there was no easy route for him to propose this idea to Namco's superiors. Ozaki suggested a novel approach for Takahashi through the Namco Digital Hollywood Game Laboratory. At the time, Namco had been following in the model that Konami had used in 1997: Konami established the Konami Computer Entertainment School to help educate new game developers which were eventually hired in Konami, and several of the experimental ideas founded by the School during this time became products within the Konami Games & Music Division (later, Bemani) that were highly successful, including Beatmania, GuitarFreaks, and Dance Dance Revolution. Namco hoped the Digital Hollywood Game Laboratory would follow a similar path. At the time, Masaya Nakamura was principal of this school, and oversaw one senior thesis class where the students were being trained on 3D modeling towards producing a game prototype with the help of other
