Hi
I started using cesiumjs recently and been working on it mostly on weekends. I have created fourteen Cesiumjs beginners tutorial videos (screencasting) and I have uploaded it to my youtube channel. Many of these videos were based on cesiumjs.org websites tutorial. I would love to get feedback. You are free to distribute the videos.
