I believe it does exactly as intended: developing spatial reasoning. I don't know if it is the most affective way, and it may not be for everyone, but it has definitely been affective for me. I have begun to internalize how to think about representing three dimensional on a two dimensional surface. Now, when I am drawing, the lines on the page almost "feel" three dimensional. This is so fundamental that it can't be over emphasized. No matter what medium you use, understanding this illusion is fundamental.
What the program isn't is a method of learning how to draw pretty pictures. But after you have done Drawabox, drawing those pictures gets easier. So when you ask for before and after pictures, I don't know if I can provide those. I have used other programs to improve specific aspects of drawing, but Drawabox laid the foundation.
Also, it is free and online. Hope this helps.
