Breathing stone prototype mark 2

Going to try and make it glow.

Maybe we want to have the stone glowing softly. Worth a try?  LEDs are a bit brash so I need a diffusing layer. Tried sanding acrylic but did not produce the right effect. Now I want to try using a Gelcoat reesin to make the top surface. Here we have just made a silicon mould. I am waiting for the Gelcoat.
