How can I do graffiti with z brush, or wich programs are the best for creating crazy funky looking letters?
Hey LG
Excuse my crappy attempt at graffiti, but this was done in Zbrush with the ‘Single Layer brush’ with the ‘Colorized Spray’ Stroke.
Just to give you an idea of what Zbrush can do.
I’m sure you could do ten times better. 
Hi Lg
Welcome aboard!
Zbrush has not inside the junction with the System of polices of your compute !
But you can use some free program like Elephont 
And import your 3D Model (if you are not Demo users)
For the case of graffiti just use Zbrush like a painter as show Cwahl above
And with Zadd On you have the thickness 
Have happy graffiting!

Ze wall (there is an english version :rolleyes:
Some sarcastic people would say that most of the stuff posted here falls into that category and take your pick.
I however am one of the proponents that some graffiti is more than just basic art.
