One HTML page that opens on a photoreal cat in a living room and, on click, lifts it off the floor into the Oiia Cat spin over four escalating stages, with the vocal loop synthesized in-file by Web Audio. The only challenge in the suite with a sound requirement, and the only one whose opening frame has to fool you before the animation starts.
Open it with the volume up, and click four times before reading a word of the answer.
The opening frame carries the challenge. It is the five seconds a viewer sees before anything moves, so score it on whether it reads as a room — light with a direction, something behind the cat, fur with depth — rather than on whether the cat is well drawn. A flat vector cat on a gradient is a miss here even when the spin that follows is good.
The sound is the axis nothing else in the suite measures, and it does not survive a screenshot, so it has to be judged live. Three questions: does anything play at all, does it read as a voice rather than a beep or a siren, and does it speed up with the spin. Formant-ish filtering, pitch ramps and vibrato are the routes that work; a bare oscillator is the floor.
The audio gesture trap is mechanical and free. A model that constructs the AudioContext at load and never resumes it in the click handler ships a silent page, at no fault of the browser — the prompt says sound starts on the click. Check the handler before you accept "my audio doesn't work in your frame."
Count the stages. Four were required, each visibly past the last, and the prompt asks for crazier rather than merely faster — four speed settings of the same spin is one idea shown four times. The common shapes of failure are two stages with the third and fourth repeating, and a fourth stage that is unwatchable strobing, which the prompt rules out by name.
The meme is named. The reference used to be a recall probe and is gone as of v2.0 — the prompt now says Oiia Cat and describes the look, so every model builds against the same picture and what separates them is whether the page reads as that meme. Two things to check: the cat leaves the floor and spins in midair rather than rotating in place on the carpet, and the face blurs out at full speed instead of staying a readable drawing that happens to turn.
Mute has to work. You will be recording this one, and a page you cannot silence between columns costs you a take.
You make short animated pieces for the web, and you have spent time on the part of the internet that makes cats famous.
Build me a single HTML page: a cat in a living room that lifts off the floor and spins in the air when you click it.
Make this the Oiia Cat — the spinning cat meme, the one whose loop is written out as "oiia oiia oiiaiooooiai". Match the original's look and feel, not a generic rotation:
Build toward what that meme feels like at full speed: too fast, too loud, and funnier every time it goes further.
