Abstract: An interactive computer game is described which works in conjunction with a number of physical modules that a user can connect together in different ways to form a coherent physical whole object. The game receives data from the object via a wireless link, the data identifying at least which modules form part of the object and updates game play based on the data received.

In an embodiment, this interaction comprises re-arranging the modules or swapping modules to form an object with a different visual appearance, moving all or part of the object and/or interacting with a sensor on a module in the object. The game may receive further data from the object during the user interaction.

Abstract: Optical diffusing films are made by microreplication from a structured surface tool. The tool is made using a 2-part electroplating process, wherein a first electroplating procedure forms a first metal layer with a first major surface, and a second electroplating procedure forms a second metal layer on the first metal layer, the second metal layer having a second major surface with a smaller average roughness than that of the first major surface. The second major surface can function as the structured surface of the tool. A replica of this surface can then be made in a major surface of an optical film to provide light diffusing properties. The structured surface and/or its constituent structures can be characterized in terms of various parameters such as optical haze, optical clarity, Fourier power spectra of the topography along orthogonal in-plane directions, ridge length per unit area, equivalent circular diameter (ECD), and/or aspect ratio.

Having inferred the path, the game constrains a virtual or physical object to the path within the game play and renders a graphical user interface showing at least a portion of the path.
