# People make the pattern.
Independent article case study. Domain: website consumer / Design Engineering presentation.
Measured digit strips settle with digit-specific revolutions and durations. Twelve original geometric portrait cards use stable local IDs and container-relative collage positions, then orbit only after the count completes.
## Attribution and evidence
Studied: [Building an Animated Testimonial Hero Using the GSAP Timeline and Dynamic CMS Data](https://tympanus.net/codrops/2026/08/18/building-an-animated-testimonial-hero-using-the-gsap-timeline-and-dynamic-cms-data/), Jonas Arleth. Article SHA-256: 7662accf1e5f92ddd08a601fd44e4ce29a59db97a271ca6dfeb15d119da7ef2c. Analysis SHA-256: 4cbcb644c9af5f89eb3aacc4b521bf4acd613acda1bf0fe27ae3f4d0f25ab11a. Source revision: 868a25dc679f89dd12703d7197e10f70d46ac9f1dd45557b67213d67054595aa. 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. Seven public counter/layout fragments and a free generator link are present. No original Webflow/CMS project export was acquired. The optional course sales-page link does not establish paid access to this case study.
No original article prose, code, artwork, source project or screenshot is distributed here. The authored-code MIT notice applies only to the independent implementation. Use independently owned or cleared portrait assets. Keep the demonstrated local dataset distinct from a live CMS integration.
## Initial state and controls
A locally supplied count rolls into place before a cast of original geometric portraits begins its depth loop. Resize the collage without changing its proportions.
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 |
| --- | --- |
| total | 1872 |
| width | 100 |
| speed | 0.6 |
## 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.

Applied canonical sections and current-authoring hashes are recorded in KNOWLEDGE.json. No design-terminology records are relied on. External references within canonical guidance were not independently rechecked by this implementation lane; only the local sections and article capture identities were checked. Root Layout corpus, Game UI, provider integrations and publisher export claims were rejected as outside this lane.
BEHIND THE EXAMPLE
이 장면을 만드는 원리
07 / Rolling digits & member collage · renderMembers
The accessible member count comes directly from the local numeric input; digit-strip position is presentation of that same target.
- 이 예제에서는
- Measured digit strips settle with digit-specific revolutions and durations. Twelve original geometric portrait cards use stable local IDs and container-relative collage positions, then orbit only after the count completes. This binding describes the authored study and does not verify the original project.

Change total to 0, 9 and 12034; replay each count.
살펴볼 변화The accessible label is immediately the exact target; visible strips settle to the same digits without a live CMS claim.
07 / Rolling digits & member collage · renderMembers
The count settles immediately and portraits return to a static collage when reduced motion becomes effective.

Enable Static view while the count or portrait loop is playing.
살펴볼 변화The entered total stays available and the full static collage replaces the moving loop.
07 / Rolling digits & member collage · applyMotionPreference
One effective preference owns CSS and script playback. The initial view is stationary, and manual controls retain the study values.
