Motion Blur

 Picture of a cardboard flower, you can see the motion of the flower in the liter tones of yellow. The color creates a magenta purple in the background.

 Blurred picture of a car on California street. I like this because the shadows (especially on the car) gives an old fashioned cartoon-like feeling.

 The blur of the blue flower, gives a ghostly trail of where it once was.

The colors and blur describe what the sign says.
