Beautiful art can be both awe-inspiring and intriguing. Some of it simply awakens the creativity or beauty inside of us all, and other stunning works of art makes us really think about deeper issues. No matter the level of intensity of the piece, great artworks cause most people to stop, if even for just a moment, to have an emotional experience. And this experience, these emotions, will be re-lived every time the viewer encounters that piece of art again.
This is why art created to raise awareness for a cause can work so well. The art work creates a powerful and lasting emotion that moves the viewer to action. Just as with melodies, visual images stick with us more than just words. Most artists are very aware of this power that art contains, which is why so many use art to express themselves, make a statement, or, like the ones below, illicit movement for a cause.
