Grab and drag red circles. Repeat to make your art. Draws fractal triangle between circles, wherever you place and replace them. Spacebar to hide red circles. Flag to reset. Automatic to 1 doesn't let you make your own art.
Drag red circles, repeat. Draws "Sierpinski" triangles. Each is fractal even when triangle is distorted. Pen uses darn little code. Circle sprites use more code. Aggregates of triangles really break the symmetry, often in a beautiful way.
