“Each Line One Breath” is a series of meditative drawings by artist John Franzen. He calls them morphogenetic freehand drawings.
He starts with a straight line all the way down a page, and then slowly draws another line beside it. He tries his best to copy the line exactly but inevitably there are tiny imperfections. These “mistakes” are amplified as he copies each new line, and the drawing begins to reveal itself like a curtain. (text via booooom.com)
