Visual Programming for the Visually Impaired

The blueprint code is just a text file in XML type format so you should be able to parse it pretty easily. There is actually a pretty good website where you can paste in blueprint code and it will display the nodes in a web browser, or you can create blueprints in it.

I do like the idea of physically building the blueprints but it sounds like it would get very difficult to navigate after a while, and there are hundreds of different blueprint nodes, and you would need dozen’s of the same node’s as well. How do you intend to get around this issue?

It seems like an audio reader would probably solve this problem a bit better than a physical solution. Or perhaps a braille screen of some sort?
