Key takeaways

An author created animated demonstrations of sorting algorithms on a phone using Claude Artifacts and added a feature to run all demos at once.
The demos include bubble sort, selection sort, insertion sort, merge sort, quick sort, and heap sort.
To add Python's Timsort, Claude was used to clone the python/cpython repository and consult Objects/listsort.txt and Objects/listobject.c.
A "run all" button was added that displays smaller animated charts for every algorithm in a grid and runs them simultaneously.
After the design update, the author preferred the new color scheme and the "Run all" button produced the intended grid-running effect.

Is the implementation (including any Timsort port) behaviorally correct relative to its intended reference, and what tests were used to validate it?
What portion of the final code and UI was authored directly by the human versus generated or modified by the LLM tooling environment?
How does the "run all" grid behave under device constraints (performance, memory, frame rate), especially given simultaneous animations on a phone?
What inputs, parameterization, and visualization choices (array sizes, initial distributions, speed controls) are used across algorithms in the demos?
Is the project publicly accessible (e.g., URL/repo) and reproducible by others using the same tooling?

LLM tooling that supports rapid interactive UI prototyping on mobile could see increased adoption as creators use it to build and iterate educational demos quickly.
Demand may rise for developer tools that let users ground implementations in authoritative upstream repositories, enabling more complex ports like Timsort with reference guidance.
Side by side batch visualization features such as a run all grid may become a common expectation in educational and algorithm visualization products, favoring platforms that make this easy.

Public release of the project with reproducible artifacts shows others can build similar multi demo interactive visualizations using the same LLM tooling workflow.
Evidence of behavioral correctness via tests or parity checks against reference implementations, especially for any Timsort port guided by upstream files.
Demonstrated stable performance on phones when running simultaneous grid animations, with acceptable frame rate and memory use across supported devices.

Validation finds the implementations diverge from intended algorithm behavior or Timsort parity, undermining trust in LLM assisted code generation for this use case.
Run all grid mode performs poorly on typical phones, causing low frame rates or crashes, limiting real world usability of simultaneous demo comparison.
Workflow is not reproducible or requires extensive manual edits, indicating limited generality of the claimed rapid prototyping advantage.
