But more than just a simple camera-based app, Woorld is using Google's Project Tango which you might not remember.
Announced a couple of years ago, Project Tango uses some special hardware on top of an Android device to map an entire room on your mobile device. Thus, every AR experience is more accurate. It even features a depth sensor and a wide angle camera.
Takahashi's Woorld is described as an experimental game that mixes the physical and digital world and which transforms everyday objects in fun toys.
We're poised to hear more about this at Google I/O this week but it's fun to this another Takahashi game.
