Which device uses a strip of pictures arranged around a spinning cylinder?

The device that uses a strip of pictures arranged around a spinning cylinder is the zoetrope. The zoetrope consists of a cylindrical drum with vertical slits cut into the sides. Inside, it holds a series of sequential images on a strip, and as the cylinder spins, viewers look through the slits to see the images in quick succession, creating the illusion of motion.

This method of displaying an animated sequence capitalizes on the persistence of vision, where the eye retains an image for a fraction of a second after it has disappeared. Thus, when the images are viewed through the moving slits, they blend together in the viewer's perception, producing the effect of motion.

While the praxinoscope and phenakistiscope are also early animation devices, they use different mechanisms. The praxinoscope employs a spinning drum with mirrors, and the phenakistiscope uses rotating discs with slots to view images being played out in synchronization with their rotation. Flipbooks, on the other hand, are a series of images bound together and manually flipped through to create an animated effect.
