Plateau was born in Brussels in 1801. His research on visual perception inspired him to invent the device. Google said he studied law first, and then became one of the most famous scientists in the 19th century. He was remembered for his work in physiological optics, especially the effects of light and color on the human retina.

Google said Prato's Ph.D. thesis details how images are formed on the retina, pointing out their exact duration, color and intensity. On the basis of these conclusions, he made his stroboscopic device in 1832, equipped with two disks rotating in the opposite direction. One disc is evenly divided into 16 sectors and a series of dance movements are painted on the other. Google said that when the two rotate at the right speed, the images seem to blend together, creating the illusion of dancer movement.

Like modern GIF animation, "trick" can only show a short continuous cycle.

Graffiti art was produced by animator and filmmaker Olivia Huynh to reflect Prato's style. Google said it was the first to show different doodle works for different device platforms (desktops, mobile devices and Google Apps).
