I have a dream where you can code Lisp via diagrams, this is a nice aproximation of it.

Anybody ever tought of that? First you draw diagrams of Lisp metaphors with Lisp, then you can code Lisp by creating diagrams and evaluating them. Thanks to the almighty powers of Lisp you could then draw or code meta-diagrams to guide diagram modelling. The biggest challenge, imhhho, is getting the Lisp diagram representation right to make it sound.

I was thinking in joining a Lisp open-source project to get up with Lisp application coding pratices, any suggestion?
