A method, system, and apparatus, including a program encoded on computer-readable medium, for interactive training or entertainment. Each of multiple platform components interconnects with at least one other platform component and includes visual indicators, a detector substantially adjacent to each indicator for detecting a proximate game accessory, and a detector microcontroller. A main control unit receives data frames from the detectors and determines a quantity of detectors in an interconnected set of platform components based on data contained in the data frames. A memory stores a plurality of routines. The main control unit is adapted to execute a selected routine based at least in part on the determined quantity of detectors. The selected routine defines a sequence of activation of the indicators in the interconnected set of platform components.
