Building Dice Atelier: a 3D dice roller with 20 themed tables, built by two AIs and one director

Two days ago our little free-tools site had a perfectly good dice roller. Then it got an upgrade with delusions of grandeur. Dice Atelier is a 3D dice roller for D&D night: twenty themed tables — an astral observatory, a clockwork library, a neon ronin bar — each with dice styled to match. Mixed pools, dice notation (try 4d6+2), advantage and disadvantage, up to 100 dice at once. It's free, no sign-up: https://penguinwearingahat.com/tools/dice-atelier/ No human wrote the app.
