Walking Lines began with the inclusion of the drone into Herzog's process. The new tool created a new perspective plain for Herzog to work on. The driving concept for the work is the ability to use walking, something we do every day, as a medium for mark-making – to his satisfaction, making something from nothing. When enacted in the context of art, walking becomes an accessible medium to work with. This accessibility opens up a relationship between the viewer and the artwork. The viewer, if they are able-bodied, walks. By that fact, everyone who walks posses a tool of art-making.
