Motion Clouds are a set of stimuli designed to explore in a systematic way the functional response of a sensory system to a natural-like motion    stimulus. These are optimized for translating, full-field motion and are by    construction textures synthesized from randomly placed similar motion    patches with characteristics spatial parameters. The object of such an    endeavor is to systematically test a system to varying the parameters by    testing the response to a series of such textures. We show here for a fixed    set of central parameters (mean speed, direction, orientation and spatial    frequency) a cube constituted by a family of such Motion Clouds when varying    the bandwidth parameters for speed (left panel), frequency (right panel) and     orientation (top panel). Each elementary cube in the larger cube denoting    the parameter space represents a Motion Cloud and is shown as a cube to    represent the corresponding movie, with time flowing from lower left to    upper right in the right and top facets. Overlaid hue gives a measure of a    typical response for a sensory response (here a motion energy model) which    gives a complete characterization of the sensory system at hand.


"When you can measure what you are speaking about and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of the meager and unsatisfactory kind." Lord Kelvin
