Ask HN: Multi-Decade Poverty Outcomes Study Visualized with Little Sprites

I'm going crazy trying to remember the website that was on the front page of HN for a few hours or a day a couple of months (or maybe year) ago.

It was based off a study measuring the differences in outcomes for individuals who experiences poverty versus those who didn't, and it was memorable because as you "scrolled" through the story, there were tiny little 3d dudes running into their respective buckets based off their outcomes (with collisions, not pre-determined I don't think).

Does anyone know what I'm talking about? Or am I crazy.
