You know a long time ago I used to "code" in this language called LabView and it was all graphical. It was designed for electrical engineers. I remember working with electrical engineers that had no idea about coding and they would be able to build complex systems in LabView. You would drag and drop a box and attach it to another box with a connector and that would be a loop, etc. Really awesome. Maybe something visual like that, with colors, animations etc would work for kids.
