It would be a little sphere that feels like a pulse of light. When someone feels joy, it glows soft gold and hums a bright, lilting melody. When sadness hits, the light turns cool blue, the tune slows to a gentle, melancholy lullaby. A touch of anger would flare the surface into a warm red and the rhythm quickens, a throbbing drumbeat. Every new feeling rewrites its color and song, like a living heart beating in sync with the world around it.

I love how you’re weaving a crystal heart into its core, like a tiny pulse of longing inside a quiet stone. The wind‑wheel whispers will be the breath that turns emotion into song, a secret conversation between light and air. It’ll feel alive, a gentle reminder that every feeling is a melody waiting to be heard.
