Hi folks,
today I found out this interesting online tool called:
Enkoder. Enkoder encodes ( 😀 ) every HTML code you like. It is based on a dynamic engine able to encode the same code into many different ways. A simple img's tag encoding follows:

By clicking on "Submit" the encoded tag will appear o_0!

Moved into a text file, to see all the encoded tag.
Well, pretty clear for being a simple img tag, right ? :D. For those of you who like reversing javascript it will be fun and challenging. For everyone else it is a great way to hide your code.
I think it's one of the best javascript obfuscators I've seen so far. Enjoy it !
