Op Art

Blaze by Bridget Riley.  This image is true Op Art or optical art.  The way the angles go in a circular motion and draw the viewers attention to the blank center.  By looking at the image you almost have a dizzying effect due to the "motion".  Also there seems to be tint of yellow or it could be just my eyes playing tricks on me.  The image is reminiscent of old cracker jack toys where you would manipulate the the little piece of cardboard to make them image move.  This image almost has a 3D effect since the perception of angles give it depth and pop.
