'Boing', which realizes the bouncing movement of a spring on the browser, has appeared, and has been bouncing more than 1.3 million times by Internet users

' Boing ' is a browser app that recreates the bouncy motion of a ball attached to the end of a spring when it is stretched or tilted in various directions and then released. Created by

The game is easy to play: just drag the red ball on the screen to the desired position and release it. The ball will bounce around.

At the bottom of the screen, you can see how many times you've bounced the ball and the total number of times the ball has bounced around the world. Clicking 'boing heatmap' displays a heatmap, and clicking 'slomo' displays the ball's movement in slow motion.

Here's a heat map showing where the user released the ball.

Below is a video of a ball bouncing around using 'Boing.'

the internet is a place where you can't get strangers to agree on much, but you can boing-snipe them into flicking a virtual spring 1M times.
