About This Product
At rest the parrot and the cage are seen separately; turned slowly, at 1 to 2 rotations per second, the two flicker in turn. Above about 16 picture changes per second the eye can no longer separate them and the parrot appears inside the cage, which explains how film, animation and screen refresh rates give smooth motion.
Frequently Asked Questions

Once the disc gives more than about 16 picture changes per second, the two images merge; at 1 to 2 rotations per second they still flicker separately.
