Before the exhibition “An Exchange with Sol LeWitt” at Cabinet closes on March 5, artists Stephanie Diamond and Adia Millett are inviting 40 staff and visitors to eat LeWitt’s favorite lunch of pea soup and brownies without utensils this Thursday at 12:30. The communal lunch is part of their ongoing “You Are Here” project, which “attempts to bring seemingly arbitrary actions into the forefront of consciousness by encouraging participants to do something different.” Email for more information.
