~~JoY OF ArT NoUVeAu~~
Stained glass by Charles Rennie Mackintosh. He replaced the Art Nouveau "whiplash" with a vertical line. A central motif of Art Nouveau, the 'whiplash' curve is characterised by sinuous curves, usually based on an image or theme taken from nature. These curved, undulating, flowing lines are found throughout architecture, painting, sculpture, and other forms of Art Nouveau design
