Two angels with harps and halos and wings are sitting on a cloud. One

The next image uses many colors and explores the use of contrast:
Which image do you think is most interesting and creative?
Name a memorable movie or play in which nothing difficult, adverse or
negative happened. Now name a memorable movie or play in which

of creation. Anything new requires contrast as the impetus for
creation. If we define duality as contrast it may be easier to see it's
value.
