Abstract
The present invention relates to a closed finger painting system that is adapted to be both clean and reusable. Provided is a rigid base member to which a number of closed, clear, flexible bags are attached. The bags are particularly adapted to be overlapped with respect to each other. Each bag contains a colorful, transparent fluid. The fluids can be manipulated within each bag by pressing the bags with one's fingers. When the fluids in more than one bag overlap, they create an optical impression of being mixed to create new colors. Therefore, an infinite variety of distinctive, abstract designs can be created.
