A zoetrope is a pre-film animation device that produces the illusion of motion, by displaying a sequence of drawings or photographs showing progressive phases of that motion. A zoetrope is a cylindrical variant of the phénakisticope , an apparatus suggested after the stroboscopic discs were introduced in 1833.
When there is the same number of images as slots, the images will animate in a fixed position, but will not drift across the disc. Fewer images than slots and the images will drift in the opposite direction to that of the spinning disc. More images than slots and the images will drift in the same direction as the spinning disc.

Spinning tunnels depend upon creating sensory confusion between the kinesthetic system, the vestibular system and the visual system.The body's sense of the motion and the position of the limbs is provided by sensors in the joints, the semicircular canals within the inner ears provide sensory data for the head's position relative to the ground, and the eyes provide input concerning where the ...

For thousands of years, fibre was spun by hand using simple tools, the spindle and distaff.
