Geneus1 asked me to tell you that for a limited time, he has some free graffiti typefaces on FontStruct, which is a web-based application that allows users to design modular typefaces.
His work is here
http://fontstruct.fontshop.com/fontstructors/geneus1/public
and in particular you might like Graffikki, which recently won third place in the FontStruct international design competition, and Throwdown, which earned a special mention in the previous competition. DeTrayne is dedicated to Dondi and Dream.
All of his fonts at FontStruct are free for personal use, but some will be taken offline soon as he is releasing retail versions of them.
FontStruct is a pretty cool little font-fiend/typnerd community, and it's simple to sign up (it's free and you just need an email address), then you can download and make your own fonts there. All fonts are in TrueType format and can be used in any operating system that utilizes them. Each font has a license that is selected by the creator, some are free for personal and commercial usage. Most of Geneus1's are licensed for personal use only.
