Though solid diorama-making skills are crucial when you’re a kid, they don’t really pay off in the adult world. But they will this Sunday, as the Grown-Up Club will be revisiting the art — shoebox, cotton balls, hot glue, and all. Any good diorama assignment has a theme; at this event participants will be creating pieces inspired by “American Lyfe: 50 Years in the Future.” Will these be utopian or dystopian dioramas? You’ll have to peek inside to find out. The stakes are high: First place takes home $100. Winners will be judged by celebrity diorama experts (or just kinda locally known people who dig a good craft project), and beer will be plentiful.
