"Open your laptops," she said. "I'm going to show you how to build a universe, one triangle at a time."
"Let's just say… the notes wrote themselves."
Professor Elara Vance stared at her laptop screen, defeated. On it was a single, blinking cursor on a blank PowerPoint slide. The title read: "Lecture 9: Ray Tracing." Below it, in smaller font: "Or, Why Your Reflection Doesn't Look Like a Funhouse Mirror."
It was 2:00 AM. The final exam was in 48 hours. Her 200 students were counting on her to explain how light, math, and silicon came together to create the illusions of Cyberpunk 2077 and Toy Story .

The PPT was finished. Forty-two slides of interactive, animated, crystal-clear explanations. No walls of text. Just pure, moving, beautiful geometry.
Elara glanced at her laptop, where a single vertex was still lazily spinning in the corner. She winked.
