picture description: Rollercoaster at an amusement park. This picture is also a representation of formal art concepts. Green and red are complimentary colors. They are well used in this picture, the green shapes are round and organic, the red shapes are straight and inorganic. The sweeping green shape, highlighted with the yellow rollercoaster cars, moves the eye from top left (where English reader's eye always enters a picture) to the bottom right, is drawn upwards by diagonal lines to the curving green shape, which then takes the eye to the left of the picture again. The next curving shape send us to the right again. Meanwhile, the straight vertical red lines in the background keep a visual tension going. Very effective photograph, it would make a wonderful subject for a painting.
