ABSTRACT:
A magnetically actuated visual display board comprises a grid array of open ended chambers. Display configurations in each chamber utilize a magnetically responsive sliding element to move a display loop to alternate between two different display surfaces to create a desired visual array. A magnetic rod passing a chamber moves the sliding element within the chamber.
