Abstract

A persistence of vision device is provided and includes an element shaft, wherein the element shaft includes shaft front surface and a shaft length, and wherein the element shaft is flexible in a sagittal plane. The device further includes at least one light source, wherein the at least one light source is associated with the shaft front surface and extends along a portion of the shaft front surface length and a processing device, wherein the processing device is communicated with the at least one light source to control the operation of the at least one light source. Furthermore, the device includes a displacement device having a displacement device shaft movable in the coronal plane, wherein the element shaft is connected to the displacement device shaft such that the element shaft is movable in the coronal plane.
