1. A method for using visual effects within a three-dimensional (3D) display environment to indicate a usage context of a computational resource, wherein the computational resource is represented by a 3D object in the 3D display environment, the method comprising: determining the usage context of the computational resource; determining visual effects corresponding to the usage context to be applied to the 3D object which represents the computational resource; and applying the visual effects to the 3D object so that the usage context of the corresponding computational resource can be determined by viewing the 3D object within the 3D display environment.
