All components

A velvet-furred pyramid, cube, gem, heart or orb with bead eyes that can wear glasses, a hat or headphones. Listening breathes a soft aura, thinking sends light around its edge and across the fur, and speaking swells with the voice.

An assistant persona as a drop of liquid metal on the GPU: it mirrors a softbox studio, tints to any colour and shimmers at the edge. Idle flows, listening draws ripples in, thinking rolls swells under the surface, speaking ripples out.

A pixel creature for an assistant: blob, ghost, bot or cat on a 32×32 grid with dithered shading and a glow. It blinks and bobs when idle, opens wide to listen, glances up with ticking dots to think, and talks and bounces to speak.

Assistant personas as orbs of light, shaded like Edge Cloud on the GPU. Idle breathes, listening pulls rings inward, thinking lights drifting veins around a beating core, speaking wobbles and flares with the voice. Persona colours fade.
