Ben Sack's drawings posit his viewers above sprawling megalopolises. As we gaze down, thousands of buildings appear to go on for miles: Sack painstakingly renders each detail with pen and ink. Judging by the time lapse videos he posts of his pieces, he seems to draw them freestyle without much pre-planning. The process video of his recent piece, Chronoglyph (pictured above), reveals Sack filling in loosely sketched circles with elaborate line work. With each drawing standing close to human height, Sack's work invites viewers to get lost in the many nooks and crannies of his fantasy cities.
