themes or new gui layouts for bugzilla ?

[news at merkleonline.de]

Hi again,

okay i have downloaded deskzilla and that GUI is very nice IMHO. :-)
I also looked at mantis which has also a nice GUI (okay personal taste).

Question: 
are there other themes or new gui layouts for bugzilla ?
I know that via templates i can modify everything, but I would prefer some already exisiting solution ;-). 
Any hints appreciated...

kind regards,
Bernhard.
