Question Nexus theme for Xperia devices?

I have been looking all over forums to find a nexus theme for my Sony Xperia Z1 and to my surprise it seems like there isn't one available.

I know that there is a guide on how to create one here: http://www.xda-developers.com/androi...-xperia-theme/
but I don't have sufficient graphic design knowledge.

Has anyone stumbled upon one or created one?
