AFrame web VR is really attractive.
I spend several days on playing with all the API's that aframe provide me.
There are a lot of open source project that already made by other developers.
The animation they made are soooooo attractive.
The 360 Image is also really good:
I learned a lot from other people's code.
Finally, I make my own Starting Kit based on their example, and I also add some advance features:
Please go and play with it: A-Frame web VR
It doesn't look that fancy, but I think it is easier for a beginner to understand.
I also saw other people made a Starting Kit for AFrame, too.
However, I'm prode to say that mind is much better the old one.
