A retro music visualizer or a row of dancing cats above the prompt, driven by your session

An eight-row band above the prompt animates at about 30 frames a second, like an old media player's visualizer, and your session is the music. Sending a prompt kicks the bars, each tool call kicks a band picked by the tool's name, the beat picks up while Claude works, and a finished turn sweeps across the whole width before things settle into a slow drift. There are two modes. Plasma is a flowing color field with equalizer bars and peak markers. Cats is a row of pixel cats bobbing on a moonlit rooftop: a tool call makes one of them jump or look away, and now and then a mouse runs across the roof. A line under the band shows whether Claude is working, the last tool it called and how many calls so far.
