Both of these links are examples of stroboscopic motion. Stroboscopic motion is an illusion when lights or images are flashed quickly and the brain perceives them as moving. A great example of stroboscopic motion is a flip book. One image is quickly replaced by another image with slight alteration to the original ,resulting is a 'motion' picture. The brain perceive these flashing images as a whole rather than seeing the pictures as separate images, following the concept of Gestalt Theory.
