In this workshop the children watched a short video about Bridget Riley, one of the most famous artists of the Op art movement. The video introduced the concept of optical illusions, typically illusions of the impression of movement, which is central in Op art artworks. Then the children had time to browse various books and familiarise themselves with different ways of achieving similar results, through the appropriate combinations of geometrical patterns and colors.
Afterwards, the children had opportunity to create different ‘colors tracing’ Op art pinwheels, to give more swirling movement to their patterns, and to stimulate even more the involvement of the observer. Just like real Op artists! The results were mesmerizing optical illusions.
