• Before we can draw anything, we need a window to draw on ...

• size command:

• • size( width, height )
  • creates a window to draw on

• The window size is based on pixels

• • height, width: number of pixels
  • default is (100, 100) / used if you forget the size command
  • coordinate system: (0,0) = upper left / (width, height) = lower right
