A post with 953 likes and 54,033 views describes being 'blown away' by the quality of Three.js landing pages Opus 5 produces, noting that a bare instruction like 'orbit using mouse' is enough to yield a working 3D parallax effect and 'add particles' behaves similarly. It is the low-effort counterpart to the multi-hour, 5,500-line Three.js experiments circulating earlier this month — the interesting claim is not the ceiling but the floor, that short imprecise prompts now land WebGL scenes without iteration. Single-source and anecdotal; no benchmark or reproducible artifact accompanies it.
