# Meet Pip. Find the beat.

Independent article case study. Domain: website consumer / Design Engineering presentation.

An original seed character uses grouped SVG pivots, a clipped ground plane, a continuous pose evaluator and a discrete variable-hold frame selector. The flag inherits the hand transform.

## Attribution and evidence

Studied: [Reverse-Engineering Claude AI’s Mascot Animations with SVG and GSAP](https://tympanus.net/codrops/2026/05/05/reverse-engineering-claude-ais-mascot-animations-with-svg-and-gsap/), Ayotomiwa Wale-Durojaye. Article SHA-256: 7a54d783519c848f0cb1f767dc29504f9ef3db0d53d8d8a526f247772ac7573b. Analysis SHA-256: 4cff4c283df1fef9d25ae50866552ef2f19006a48144a47c274a9bac027ae816. Source revision: 44c092ffafe0cd6f61ed5abb28f5104790969a34f4ff7166bd6084dcb8ff2b2c. The revision hashes the article/analysis hashes, the analyst principle and code-block evidence references; it identifies studied evidence, not a claim that the original demo executes.

Original acquisition: unresolved. Original license: unverified. originalSourceAcquired: false. Eleven public animation fragments and the author's demo-page link are present, but no complete downloadable source package or grant for the replicated original mascot artwork was established.

No original article prose, code, artwork, source project or screenshot is distributed here. The authored-code MIT notice applies only to the independent implementation. Create distinct original character art and retain the article's technical attribution. Do not label the result as the author's recovered frame set or Anthropic's original animation.

## Initial state and controls

A newly drawn seed courier jumps, leans, waves and celebrates. Compare continuous movement with uneven frame holds, then inspect the prop’s attachment point.

The page starts stationary. Play motion, where present, advances this study’s presentation until paused; text, bounce, portrait, orbit, strand and mascot motion loops, while the event composer stops at its endpoint. Scroll studies advance through ordinary document scroll or their chapter buttons. Static view stops time-based motion; manual controls still inspect values. The three scroll studies instead show every chapter in ordinary reading flow. Pointer parallax centers its decorative layers.

Initial control values:

| Control key | Value |
| --- | --- |
| action | jump |
| sampling | continuous |
| holds | weighted |
| phase | 35 |
| speed | 1 |
| guides | off |

## Running and editing

Open index.html directly. It contains all runtime code and visuals and needs no package install, account, network, remote asset or browser-origin storage. Edit its inline style and script to change the downloaded page. styles.css and script.js are reference copies of the inline source; changing those copies alone does not change the running page. Repository regeneration overwrites index.html and all generated copies, including any manual edits. Keep a separate copy when editing a download. The repository authoring modules in vendor/codrops-article-studies/scenes-*.mjs and runtime.mjs regenerate these copies through node scripts/build-codrops-article-studies.mjs. Repository regeneration also needs the private source evidence; downloaded-page execution does not.

## Verification boundary

This generation passed the captured article/analysis hash checks, exact ID membership, local canonical Markdown anchor/hash checks, implementation-symbol checks, JavaScript parsing, semantic main/title counts, duplicate-ID checks and runtime URL/storage exclusion. The manifest codeFiles entries identify every emitted file by SHA-256. Each code symbol is a searchable named function, not a claimed executed call trace. Proposed checks are in KNOWLEDGE.json. runtime_verified: false. SG artifact capture proves only a recorded initial render; no interactive runtime, keyboard, accessibility, comfort or performance result is claimed.

Manual Chrome interaction is blocked by extension UI in this session. No alternate browser-control route was used. Preview sizing is native responsive width. Initial-render captures are tracked separately at site/artifacts/full-import/preview-posters/index.json and site/artifacts/full-import/preview-posters/visual-review.json in the repository. No capture receipt is bundled with this download. The bounded initial-render matrix requests all 21 studies at 320 pixels and three representative studies at 1280 pixels; the separate poster surface is 640 × 420. The authored CSS also adapts at 375 and 768 pixels, without claiming those widths were captured. A width request does not mean that capture exists or passed. Motion starts on explicit playback; system reduced motion and the Static view switch stop it.
