Interesting. In the local hackerspace, for several years, I watched many students struggle with a (very fine) graphical drag-n-drop programming tool known as StarLogo TNG[0] (and Logo variants). In the end, it seemed the brighter students destined for real programming were relieved to get into a text editor. The "success stories" focused on people who could not otherwise program, but the cost was imposing too much abstraction on the brighter users. So I think it's a hard problem, and thus a very worthy one to pursue. [0] http://education.mit.edu/projects/starlogo-tng http://education.mit.edu/projects/starlogo-tng
