Zanatorian Wallpaper

Finally designed symbol for the adeptus mechanicus Zanatorian cult

After creating a Peacekeeper Wallpaper based off farscape I decided to create a wallpaper for the Zanatorians so i started with a graphic wallpaper background and inserted the following...
The Computer Code,
All Of The Text,
The Machine Cult Icon,
and the horizonal strip of mechanicus images from the Horus Heresy books. This will change when i have a few miniatures to photograph.

However i'm still stuck for an symbol for my machine cult problem is that it has to be something i can slap on a vehicle and space marine shoulder pad. Any suggestions?
