I have this glass sphere model of the universe [1] showing galaxies as tiny bubbles. It’s beautiful and humbling (it represents about 1/100 of the observable universe).
So, it's clear glass containing a 3D model of the local universe? I'd love to know how they make them. (The website doesn't say much, although the linked Kickstarter says "Captured Into Glass With a High-Powered Laser".)
