I need some help from gfx artists please

Well, i'm making a sig for Djinni@d2jsp (maybe some of you know him) and he want a last special thing in the sig before (i hope^^) buying it.

Here an example that he provided to me:



The "special" thing is in the name: the the red part witch is moving inside the name.
If someone knows how to do this, or give me some tuts links, it could help me a lot.

Thx.



edit: arf sorry i found a nice tut to do this :/
plz someone close ^^
