A graphical user interface provides a series of nested spherical surfaces representing a surface and/or human development at differing times in history and prehistory. An embodiment of the present invention, a knowledge web (K-Web), comprises a new, “multiple-intelligences” learning tool aimed at encouraging depth of thinking and understanding in numerous content areas. The K-Web optionally does this by presenting content in a dynamic structure having a multiplicity of interconnections that, used in conjunction with other input and display devices, is readily accessible in many different ways to many different intelligences and cognitive styles, and thus aid in the visualization of and collaboration on “wickedly complex” problems, such as Global Warming and Third World development. It may also be used to predict the outcome when combinations of unrelated individuals, events, and technologies are brought together.
