Anyone know some cool rolling techniques?

[snoopduo]

I'm gettin kinda bored of just skinning up a normal joint and wanted to know if there was any other decent techniques when rolling??
I can already back-roll (the skin is the other way up, peel paper off, etc.) but that's basically all i know of
Can anyone give me some help?
* I've heard people using filter tips when rolling hash, is this true?

These are some cool videos from the internet:

I'm not a joint smoker so never tried them out or can give any real tips myself, but watching these guys roll 'em up makes me want to smoke a doob right now.
