Starter Worlds for Three.js
These are the main "Starter Worlds" that use the Three.js library (which tends to give the most advanced graphics).
You can Clone and Edit all of these and change their code. Look for a section at the top called the "Tweaker's Box". This contains the easiest things to change.
