You May Have Heard Of The Shibuya Crossing,

for no other reason, 

than it is the busiest pedestrian crossing in the world, this is it above in action, and what reminded me of it was this, a GIF made by graduating art student Shun Onozawa as part of his graduation thesis project, titled “Movement Act,” a total of 16 balls are loaded onto a star-shaped platform that continuously “juggles” the balls from side-to-side. The 16 balls move back and forth from 8 different directions, all passing through the middle, yet never colliding, 

after building out the hardware, Onozawa spent 4 months testing his contraption and making slight adjustments until he finally arrived at the golden formula that would allow all 16 balls to continuously move through his device without ever colliding, Onozawa happens to also be a juggler so he was able to combine his hobby with his art studies in creating his graduation thesis project, Onozawa is a graduating senior at Tokyo University of the Arts, which is currently hosting an exhibition of senior thesis projects at Tokyo Metropolitan Art Museum, the exhibition is open to the public through February 3, 2019, what a neat GIF, I keep looking as I am sure one will collide, but they never do!
