This is just another exercise to test your comfort level at working with the triangular grid. The task is to fill all the nodes of the grid. The first node is selected arbitrarily and becomes the last selected node. After that, when you click on a node, the applet computes the product of that node and the last selected node. If the result has not yet been selected, it is selected now and becomes the last selected node. If it was selected previously, the move is judged as a misstep.
(The product of node 1 and node 2 is the node obtained from node 1 by clockwise rotation through 60° around node 2 modulo the grid.)
