Mad Scientist cyborg Concept

This is one of the concept designs I am doing for a project that is currently in production for a independant short Film. This is a concept for a scientist who atemps to transform himself in a cyborg (for kicks I guess). That large battery thats plugged into the back of his neck is ment to some sort of life support for I made based on the story. Hope you guys like and if you can think of any ideas or designs for cyborgs I'm open to suggestions =]
