"Open your laptops," she said. "I'm going to show you how to build a universe, one triangle at a time."
Just then, the screen flickered. The cursor began to move on its own, typing furiously. // INITIALIZING VISUALIZATION SEQUENCE // Hello, Professor. Let's fix this. Elara choked on her coffee. The blank slide dissolved into a wireframe grid. Then, a single, glowing vertex appeared. Step 1: The Point (A lonely pixel on your screen). The vertex started bouncing around the grid, leaving a trail of light. Step 2: The Line (A connection between two lonely pixels). Two vertices appeared and a bridge of light snapped between them.
