问题
I am trying to achieve a look on a Wordpress website which has a moving smoke effect in the background like this example http://hk.qeelin.com/collections/
I have seen that this is in Javascript, but I am unsure how it's working? Does anybody know how this look can be achieved please?

There are two other ways to do that that comes to my mind right now: canvas + particles and a sequence of .png files.
