An information access system and method are disclosed. A system includes a user input device and a graphical user interface responsive to commands from the user input device. A plurality of graphical structures is displayed in the graphical user interface. Each graphical structure is defined by three or more spatial dimensions, the intersection of which defines a segment. Each segment represents a defined group of information associated with the intersection of dimensions. Each group can be created manually, or defined algorithmically. The system further includes one or more controls displayed in the graphical user interface, responsive to the commands generated from the user input device, and configured for graphically manipulating selected segments of the one or more graphical structures.
