Op Art is short for Optical Art, art that "tricks" the eye. This project is one that kids enjoy as they see the results of their line and pattern choices. It has a great mathematical connection when revisiting concepts like even numbers, AB patterns, shapes, perspective, etc.
This time we incorporated technology for those who wanted to try it.
Students were allowed to use a digital camera to photograph a pose that they thought would add to the visual interest of their work.
