This is a fractal called Sierpinski's Gasket. It is a triangle within a triangle within a triangle... etc. 1) Click three spots to make a triangle, 2) Then click the green arrow To move a specific corner, click it, then click where you want to move it to. How it works: the spider wants to get to the three points, but can never decide which one to go to. It picks one at random, gets half way there, and then changes its mind. At that point it picks a new fly, and goes after it. When it gets half way there, it picks a new one. Every time it changes its mind, it leaves a dot.
