Press space bar to draw the fractal. Press c to clear. Move the dots and change the depth. It doesn't work it the pen moves outside of the screen (since it doesn't). It doesn't work well if the first and the last vertex are too close to each other, since the distance between them is used when scaling.
A generalised version of Recursive 1: http://scratch.mit.edu/projects/10687761/ Edit: The repeat-loop inside the recursive block is replaced with yet another recursive call. used at: http://www.malinc.se/math/fractals/mainen.php
