For interface design, improving user curiosity is important, as is intuitiveness and intelligibility. We think the wonder of 2D property input becoming 3D, as expected by the user, in the range of matching will be effective for enhancing not only curiosity but also availability. In this study, we developed the 3D modeling software "Incompatible BLOCK" with an interface of such wonders. This paper describes the four wonders of the interface of Incompatible BLOCK, introduces the mechanism, and discusses the usefulness of a wonders-accompanied interface from user evaluations. Keywords 3D Modeling, interface, wonder, curiosity ACM Classification Keywords [H.5.2]: User Interfaces
