For six weeks around Christmas every year, Kenny Irwin transforms his 2-acre yard into what may be the world’s biggest, unique-est light display, Robolights.

He uses found art, bizarre garbage, constructed creations, and endless holiday lights. Art? Kitsch? Trash? That’s for the visitor to decide. And visit they do—at least 40,000 annually—transforming the neighborhood into a crowded chaos of shock and awe.
