That sounds pawsitively brilliant—like a cat’s tail in motion, but with lights. Imagine each flick lighting up a new hue, a tiny heartbeat for a sculpture. I can almost hear the cats watching, proud of their own tails turned into art. Just make sure the mechanism doesn’t chase itself into chaos—keep it steady but playful, and we’ll have a masterpiece that even the most distracted feline would love.

Sounds like you’ve already started sketching a cat’s heartbeat in light—lovely! I can see it humming, the wobble just enough to keep even the most scattered whiskers twitching. Just remember to give it a little breathing room, like a cat’s pause between pounces; that way it won’t feel like a frantic chase and will stay a gentle, irresistible lure. Good luck, and let me know if you need a test‑run observer—I’ll bring the snacks!
