a collage of four classroom scenes, each showing a teacher or student interacting with a large digital whiteboard. In the top-left, a child in a red shirt writes on a bright screen; in the top-right, a woman draws a yellow triangle; in the bottom-left, a man in a white shirt circles text on a dark screen; and in the bottom-right, a man in a blue shirt writes on a light screen. The images alternate between a four-panel layout and a three-panel layout, with text and logos appearing and disappearing.
