Pixel-game rhythm short, synced in code
A 30-second vertical pixel-game short in which Claude Opus 5.5 introduces itself, opening on the twist that it can't hear music yet hits every beat. The one-sentence prompt asks for HyperFrames and music made in code from the visuals' beat sheet.
用 HyperFrames 做 30 秒竖屏像素游戏风短视频，Claude Opus 5.5 自我介绍，开头反转「我听不见音乐，但每一拍都踩中了」，音乐用代码合成并和画面共用节拍表。
Make it yours. "Claude Opus 5.5 自我介绍" (Claude Opus 5.5 introduces itself) is the subject, and the line in 「」 is the opening twist; swap both for your own. "30 秒竖屏像素游戏风" sets the length, the vertical format, and the pixel-game look.

How it was made
The creator calls it the simplest possible prompt and says no image, music, or video generation models were called: the music is written as math (synthesized waveforms) and the animation is JavaScript. They describe the style and idea as an imitation of @nicoletang0717's work.

Look notesby Reference
A vertical 8-bit platformer: a small orange pixel hero stands in numbered worlds that explain how the music lines up with the frames, with question blocks, a piano keyboard, a beat-to-frame grid, drums on a timeline, a gem, a star, and STAGE CLEAR.

- Framing
- 9:16 with the counter bar at the top, the headline in the upper third, diagrams mid-frame, and the hero on a brick floor or a piano keyboard at the bottom.
- Sound
- Music synthesized in code from mathematical waveforms, according to the creator.
- Structure
- 我听不见 音乐。 with a ? block, 我是 Claude Opus 5.5 under four ! blocks (WORLD 1), the hero on a piano with note platforms from Do to La (WORLD 2 · 配乐, 音乐也是我写的), 120 BPM = 每拍 0.5 秒 and 0.5 秒 × 30 帧 = 15 帧 over a grid (WORLD 3 · 换算), 第 N 拍 = 第 15N 帧 on a drum timeline (WORLD 4 · 对表), 画面和音乐读同一张时间表 with a blue gem (第 44 拍 = 第 645 帧) and a gold star (第 51 拍 = 第 750 帧), then STAGE CLEAR with coins.
