All clan tags are now yellow as standard. 
these effects only work whilst in the lobby searching for a game
Currently its only avalable on the PS3 
There are also special effects for certain clan tags
RAIN = RAINBOW EFFECT OF COLOURS 
MOVE = CLAN TAG MOVES SIDE TO SIDE
.... = O MOVING A LONG THE DOTS
CYCL = NAME CHANGES TO DIFFERENT COLOURS
CYCN = RED MOVES ALONG EACH LETTER

(hard to do)
put your clan tag as **** and just as you hit start disconnect the ethernet cable/router so the prohibited notice doesnt come up, then replug it in and it will have a + moving through ---- so +---, -+--, --+-, ---+, ---+, --+-, -+--, +---.
Go on CoD to check them out. I personally think its pretty cool.
Do you no any other effects that i could add to the list?
Fortunatly glitches have been patched aswell
