Review
Clean pure-SMIL loop (no script): the spoked wheels spin clockwise, the chainring turns, and the orange legs keep the feet on the pedals with bending knees on the same cycle, while the road dashes and clouds scroll, so the loop is seamless.
The full review
Clean pure-SMIL loop (no script): the spoked wheels spin clockwise, the chainring turns, and the orange legs keep the feet on the pedals with bending knees on the same cycle, while the road dashes and clouds scroll, so the loop is seamless. It is a clear pelican (pouch, crest) with its wing stretched to the bars. The pose is a little stiff, and the wing is frozen.
Verdict by the AI judge (provisional).
OK. Finished on its own after 15.2 min and produced pelican_animated.svg.
Bugs
- stiff pose; wing frozen

- 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.

Run notes
- Mode: interactive TUI in tmux (160x48), inside bubblewrap sandbox
- Isolation: bwrap: private /tmp and /run, private PID ns; only this run dir, harness binaries (ro), opencode config, /usr, /etc bound; HOME/TMPDIR/XDG data private; the project files and other runs not mounted
