Lily Hevesh (aka Hevesh5) is a 19-year-old full-time domino artist (yes!) with more than two million subscribers to her YouTube channel. "If I want to go back to college in the future, I can," she says, "but I already have the job that I want." In this Wired video, she discusses how she makes a living, how she ignores her haters, and her approach to mammoth constructions and crowd-pleasing flourishes like "the amazing triple spiral."
