The apparent phenomenon of the human eye retaining images for fractions of a second after the light source has gone is known as Persistence of Vision. While its causes are not fully understood, it can be taken advantage of in order to create illusions which trick the mind into perceiving something which, in actuality, is very different from what the mind portrays. It has motivated many creative engineering technologies in the past and is the core for how we perceive motion in movies and animations. This project applies the persistence of vision concept to a lesser explored medium; the wheel of a moving bicycle. The motion of the wheel, along with intelligent control of discrete LEDs, create vibrant illusions of solid lines and shapes. These shapes make up the image to be displayed on the bike wheel. The rotation of the bike wheel can be compensated for in order to produce a standing image (or images) of the user's choosing. This thesis details how the mechanism for conducting the individual LEDs was created in order to produce a device which is capable of delivering colorful, standing images of the user's choosing.
