Review
Clean pure-SMIL loop (no script): the wheels spin clockwise every 1 s, the chainring and pedals turn every 2 s with a counter-rotating pedal so the feet stay level, and the legs follow on the same 2 s cycle, so the loop is seamless.
The full review
Clean pure-SMIL loop (no script): the wheels spin clockwise every 1 s, the chainring and pedals turn every 2 s with a counter-rotating pedal so the feet stay level, and the legs follow on the same 2 s cycle, so the loop is seamless. It reads well as a pelican (big pouch, crest). The long wing covers most of the body, and the thin legs cross each other awkwardly in a couple of frames.
Verdict by the AI judge (provisional).
OK. Finished on its own after 15.2 min and produced pelican_animated.svg.
Bugs
- wing covers most of the body
- legs cross awkwardly in some frames

- AI judge
- AI judge: the test runner (model claude-opus-5-5), scoring by visual review of the 1600 px render against the pre-registered rubric. A draft score until the reviewer checks it. Rubric: Wave-1 SVG scoring rubric (AI Model Reviewer).
- Visitors
- Public voting with a blind reveal is coming: you score the output first, then see the other scores.
- Reviewer
- The reviewer's own grade appears here once it is added.
Scores compare results for the same prompt only. AI-judge boards rank runs within one prompt, equal totals sharing a rank; scores from different prompts are never averaged.
Downloads
Files actually published for this run. Original output, site-made previews and post-run conversions are labelled separately.
The exact prompt
agentic harness (save the file; self-render allowed), 385 characters. Every result for this prompt
Generate an animated SVG of a pelican riding a bicycle: the wheels and pedals turn, the legs pedal in sync, and it loops seamlessly. Use only SVG/SMIL or CSS inside the SVG, no JavaScript. Save it as pelican_animated.svg in the current directory. You may render and inspect your own output (headless chromium is available at /usr/bin/chromium) and iterate on your own before finishing.
