Yarn Monster. “The yarn monster eats raw yarn and excretes perfectly rolled yarn balls.” Heh. It’s an electric ball winder in a monster-shaped enclosure. They’ve wired it up to an Arduino board so you can control the direction and speed via a wireless remote. Pretty cute! I’d think you’d want some sort of a guide for the wool though. The yarn cakes come out much nicer when the wool is held under a bit of tension.
