David Pertiller describes having Claude Code build a 15-second promo video for his fuel-price app Petroly as a JavaScript renderer instead of using a video editor: every frame comes from a frame(t) function that reuses the app's design, so the video can be diffed, translated, rendered frame by frame and even covered by unit tests on its timing.

LLM Attention VisualizationA visualization of the attention mechanism in LLMs.
Isham Faizal built a browser-based tool that shows which past tokens a language model draws on when generating each new token. The implementation uses a custom generation loop with Transformers.js and a modified ONNX model to expose internal attention values, combined with pre-generated prompts to avoid multi-hundred-megabyte download waits.
