The Skill And Talent,

of some artists,

 never ceases to amaze me, above is a a vast circular drawing titled A Single Note, it has a 12.5 foot circumference, 

 but it is not the size but the detail that is so stunning, 

 artist Ben Sack picks up a black 0.05 Staedtler pigment liner pen and begins to draw the dense, intricate details of fictional cities,

 He draws until the ink runs out and picks up another pen, and another, and another,

  using ink from dozens of pens,

 until several months later a canvas is complete, and what a canvas!

this is a time lapses video, grab a cup of coffee, no make that two cups of coffee and enjoy the video, I did! what a talent he has.
