[OC] 8 Perfect Shuffles: Shuffling a deck of cards perfectly 8 times will return it to its original order. seems remarkable, but here is the visual proof/movement of the cards. Might not fit here, but thought I would share! Some other cool phenomenon can be seen in each shuffle!

[OC] 8次完美洗牌。把一副牌完美地洗8次,就能把它恢復到原來的順序。似乎很了不起,但這裏有視覺證明/牌的運動。可能不適合放在這裏,但我覺得應該分享一下! 在每次洗牌中還可以看到其他一些很酷的現象!
