• The "Intro" menu has About and List of features and Introduction.
• Click World images to run them. See How to run Worlds.
• The "Browse" menu has lists of Worlds such as Editor's Choice Worlds.
• Run the following random Worlds. Reload for more.

• When coding, see the "Docs" menu for all the documentation you need.

Do the Starter Tutorial (P5)

• The "P5" graphics library is probably most suitable for beginners. More experienced programmers may prefer to skip P5 and use the "Three.js" graphics library (below).
• To get started with P5, work through the P5 Starter Tutorial. This shows you how coding on this site works with P5. This does not assume you have ever written a program.
• The tutorial looks at coding the following World:

• You can learn in depth how to program in JavaScript in P5 by doing the course: Foundations of Programming in JavaScript. This does not assume you have ever written a program.
• When you have done that, you can do the more advanced WebGL course (JavaScript 3D graphics in P5).
• When coding, use the P5 reference material.
• When you are finished these courses, you will be able to make Worlds like the following:

• The "Three.js" graphics library is more suitable for programmers with a little experience. Beginners may prefer to start with P5 (above).
• To get started coding with Three.js, work through the Three.js Starter Tutorial. This shows you how coding on this site works with Three.js. This does not assume you have ever written a program.
• The tutorial looks at coding the following World:

• There is not yet on this site a full course in programming in Three.js.
• You are directed to the Three.js reference material.
• There are plans to partner with the book 3D Game Programming for Kids. You can code all the examples in this book on Ancient Brain. Here are two examples from the book:

• If you have learnt a little programming, start modifying existing Worlds.
• Pick one of the Starter Worlds. "Clone" it, and edit your copy.
• The easiest parts of the code to change are in the "tweaker's box" at the top.

As you keep learning, here are some examples of what you can build on this site. Build something beautiful!

Here are some of the most advanced Worlds:
