Line Art by Paolo Ceric. The Croatian graphic artist created the images of a single spiral line. The effect works similarly to a printing process. The line spacing is larger in bright areas, while the lines are closer in dark areas.
I love the dreamy pseudo-scientific world of graphic design, illustrations and patterns created by Chad Hagen. His nonsensical info-graphics leave me uncaring what data that might - but don't - contain . it's enough that they are beautiful.
