I started learning Three.js not long ago and I was a bit sad because I couldn't find easily simple examples of Three.js
You will find here all my experiments with Three.js step by step. I still have a lot to learn so there will be probably some mistakes. Do not hesitate to contact me on Twitter or by commenting on Codepen.
All example are working with the Revision 84 of Three.js (feb-2017).
I will put all the examples on Codepen so you can directly see source codes and edit them to try by yourself.
