    Graphical J Sentence Analyzer

    Announcing a graphical sentence debugger for J: wouldn't it be great if you could actually see how a sentence executes? Instead of puzzling over some expressions like this:
       z =. 100 200 300
       +/ z + i. 3 3
    609 612 615
    you can see a picture like this:
