Lecture Hall Projection

A realistic photograph taken from the audience in a dimly lit university lecture hall, looking over the backs of the heads of three students in the foreground towards a large projector screen. The projector screen displays a layout split into three distinct vertical panels. The left panel shows vertical Subway Surfers gameplay, featuring a character running on train tracks collecting gold coins with UI elements like a score of "001022". The wide center panel displays an academic presentation slide titled "9.3: Infinite Geometric Series". The slide contains math text: "Example 3: Find the sum of the infinite geometric series. 1/3 - 1/9 + 1/27 - 1/81 + ... Solution: The series is geometric with a = 1/3 and r = -1/3. Since |r| < 1, the infinite geometric series converges. S = a / (1 - r) = (1/3) / (1 - (-1/3)) = (1/3) / (4/3) = 1/4. The sum of the series is 1/4." The slide footer reads "Dr. Larson", "Calculus II", "11/14/2024", and "7 / 35". The right panel shows vertical Minecraft parkour gameplay, featuring floating wooden blocks over a grassy landscape with a TikTok watermark at the bottom right. The room has a drop ceiling and blackboards visible behind the screen edges.
