Simulation of the visual illusion that occurs when the visual capture frame-rate is unable to absorb all the intermediary positions of a spinning object. Patterns start emerging at angular velocities that are multiples of even circle divisions.
The wheel's angular velocity increases linearly from 0 to infinity. Its constant acceleration is implemented using the force-constant force type, part of the d3-force simulation engine.
