Wendell Mossgrove is a desk companion for the Mac: a retired village postmaster, and a mouse, who floats above your windows in a transparent panel. He spends most of the day asleep. When something wakes him he waves, mutters, and gets back to sorting the post. His body is a rigged 3D model drawn in ink, so every pose reads as illustration rather than a game render. His motion comes from a set of clips: dozing, a slow sway, rubbing his hands, a cup of tea, thinking, and walking. You can pick him up and he hangs from your cursor by the scruff, swinging on a damped pendulum driven by how fast you drag. Let go and he drops and lands with a squash. Ask him something and he answers in character through Claude, then speaks the reply in a small, creaky voice. When he quotes poetry, the quotation is exact: the brain can only choose a poem by its number from a vetted anthology, never write the lines itself. He also hops onto the title bar of the front window and falls off if you move it, notices when you've worked ninety minutes without a break, keeps the seasons, and tells you the weather the way a postmaster would.

Features

• —An inked 3D body: a rigged mouse in SceneKit, lit in three flat bands with an outline drawn from a second skinned copy of the mesh, posed by clips that crossfade into one another
• —Picked up by the scruff: a damped pendulum driven by the drag's acceleration, then a fall under gravity and a squash on landing
• —Talks in character through Claude, and speaks with an ElevenLabs voice, with a daily character cap and a reserve so a shared account never runs dry
• —Exact poetry: the model picks quotations by number from 175 poems, so a misremembered line can never reach the screen
• —Perches on the front window's title bar and falls if that window moves, closes or minimizes; at night he retires to a corner nook
• —Break nudges after ninety minutes of unbroken activity, offered over a cup of tea
• —Seasonal moods that change how long he naps and what he remarks on, and the day's weather in his own words
• —A scripted demo recorder renders him offscreen at 1080p with his voice mixed in, so demo videos never need a screen capture
