When I hear "visual programming" I tend to think of Microsoft IDEs or GUI drag-and-drop tools, but this article cites a really interesting project posted previously to HN (http://news.ycombinator.com/item?id=3951255). It's kind of mind-bending from a UI standpoint. See:

Not so sure that it will really "democratize programming"

Whether you like this or feel like it's not as powerful as you'd like, try http://recursivedrawing.com/ in a similar vein with discussion here: https://news.ycombinator.com/item?id=3951255. It's simultaneously simpler and more expressive than this tool in my opinion.
