David Hockney tracks the passage of the seasons through the window of his Yorkshire home. The viewer experiences the passage of time through the eyes of David Hockney and the use of his iPad to create the drawings. The artist said several times that he hopes that people will enjoy looking at his iPad drawings.  In 2009, Hockney began drawing  on his iPhone with his thumbs. The following year the iPad came out, and he included drawing with a stylus pen.

“This medium has a great advantage because it was backlit and I can draw in the dark. I never have to get out of bed,” Hockney writes. “From about April to August, when the sun is in the north, the sun would wake me up at about 4:30 in the morning if I didn’t draw the curtains or pull down the blinds,” he writes. “I never thought I would see the sunrise without the iPhone.”
