NEWS β Did you have an Etch A Sketch when you were a kid? I did and I loved that thing. It uses special powder stuck to glass and you use two knobs to move a stylus under the glass to etch pictures.

An app on your phone or tablet is used to special tones that vibrate the Chladni plate to create interesting shapes/art. Want one? Itβs $235 from cymaticslab.com
