The quite frankly mind-scrambling work of artist Ben Sack: intricately detailed cityscapes drawn with a succession of 0.05 black Stabilo pigment liners that he exhausts and replaces many times in the months it takes to complete each drawing.
His most recent work (of which you can see much more here) is the circular A Single Note above. It’s 3.8 meters across.
Prints are available.
