The image of the rainbow has become the modern symbol for gay or homosexual pride and activism. This is a good example of how a symbol can have applied meaning throughout the world and within culture who create them and give them meaning. Symbols like these are also found within religious scripture and culture, for the same purpose.
J.K. Rowling is an inspiration to me. She shows that books can indeed cause flight of imagination and that even a single idea can change the world. Words flow, words have meaning, and words have the power for change.
