3D Pixar-style animated comedy scene inside a bright classroom. Start on a medium close-up of a bored male student at his desk with a blank notebook. Pan right, rack focus following the student's gaze out the sunny classroom window as a tiny colorful bird flutters past the glass for a brief moment. The student blinks and turns his head back toward the class. Fast whip pan left, push in to the front of the room, revealing the entire giant chalkboard now completely covered edge-to-edge in chaotic, impossible math equations. A quirky, funny teacher with oversized glasses and wild hair stands holding a chalk eraser right against the board, leaning toward the student with an impatient grin. Expressive animation, comedic timing, cinematic lighting, 4k.
