ABSTRACT:
An apparatus for producing multiple light displays comprises: a discrete light source emitting at least one primary color; a circuit for driving the light source; a flexible tether secured to the light source; a handle secured to the flexible tether; and a control actuator. The drive circuit produces each of multiple time-dependent drive signals. The handle enables a user to move the light source along a curvilinear path at the end of the tether, the time-dependent drive signal and movement of the light source together producing the light display. The control actuator enables the user, while moving the light source along the curvilinear path and without substantially interrupting movement of the light source, to (i) alter the time-dependence of the drive signal and/or (ii) select another of the time-dependent drive signals for driving the light source, thereby altering the light display.
