Key takeaways

The author created animated demonstrations of sorting algorithms on a phone using Claude Artifacts.
The updated design produced a color scheme the author preferred, and the "Run all" button produced the intended grid-running effect.
To add Python's Timsort, Claude was used to clone the python/cpython repository from GitHub and consult Objects/listsort.txt and Objects/listobject.c.
The author added a feature that runs all sorting demos at once.
The implemented demos include bubble sort, selection sort, insertion sort, merge sort, quick sort, and heap sort.

The implemented demos include bubble sort, selection sort, insertion sort, merge sort, quick sort, and heap sort.
A "Run all" button was added that displays smaller animated charts for every algorithm in a grid and runs them simultaneously.

The author requested replacing a dark button color scheme with a different color scheme.

How was correctness validated for each algorithm implementation (including stability where relevant) and for the Timsort port in particular?
What were the runtime/performance limits on-phone for single demos versus the simultaneous "Run all" grid (e.g., max array size before frame drops)?
What concrete implementation details define the demos (language/runtime, rendering approach, and how input arrays are generated and visualized)?
How many iteration cycles (and how much time) were required to reach the preferred UI color scheme and working grid behavior?
Is there any direct decision-readthrough for operators, product builders, or investors (e.g., adoption metrics, cost comparisons, or deployment context)?

LLM assisted rapid prototyping could reduce time to produce interactive, mobile friendly demos, suggesting productivity gains for teams building explorable UI education or debugging tools.
Cloning upstream repos and consulting primary source files via an LLM hints at a workflow for implementing reference accurate algorithms or ports, potentially lowering research and integration effort.
A run all grid that runs multiple animations concurrently suggests a pattern for side by side comparisons, which could generalize to product feature benchmarking or model output comparisons.

Documented iteration speed and effort such as time to build and number of prompt cycles for UI changes and the run all grid behavior.
Correctness validation approach for each algorithm, including stability where relevant, and specific checks or tests used for the Timsort port.
On phone performance measurements for single demos and the run all grid, including max input sizes before frame drops or usability issues.

Frequent correctness issues or inability to validate algorithm behavior, especially for the Timsort port grounded in CPython sources.
Performance limits on phone that make the run all grid impractical except at trivial sizes, undermining the side by side comparison concept.
Lack of repeatability, where achieving acceptable UI and behavior requires many manual iterations without a predictable process.
