There's a weird thing that happens when we talk about people dying, no matter what the cause. The 2,977 souls who lost their lives in the 9/11 attack felt overwhelming. The dozens of children who are killed in school shootings are mourned across the country each time one happens. The four Americans who perished in Benghazi prompted months of investigations and emotional video montages at national political conventions.

But as the numbers of deaths we talk about get bigger, our sensitivity to them grows smaller. A singular story of loss often evokes more emotion than hearing that 10,000 or 100,000 people have died. Hearing a story of one individual feels personal and intimate, but if you try to listen to a thousand stories at once, it all blends together into white noise. It's just how our minds work. We simply can't hold that many individual stories—and the emotion that goes along with them—all at once.

But there are some ways we can help our brains out. An anonymous visual effects artist has created a visualization that can better help us see the massive number of Americans who have been lost to the coronavirus pandemic. The number alone is staggering, and seeing all of the individual lives at once is overwhelming.

In this video, each marble represents one American who has died of COVID-19, and each second represents six days. At the top, you can see the calendar fill in as time goes by. Unlike just seeing a grid of dots representing the visual, there's something about the movement and accumulation of the marbles that makes it easier to see the scope of the lives impacted.
