procedurally generated landscape

Nothing really works but I'm submitting it to the Lisp Game Jam anyway, since the game jam instructions advise us to submit failed projects as well as successful ones.
Life got in the way and I just haven't had time to complete any of this.
I intended to combine several pieces of code that I had previously written in other very different languages, converting them to Racket Scheme to make them compatible.  I've managed to convert part of one of them by hand, one of the state-transition tables for one of them.

The plan was to procedurally generate a landscape with a plausible river network for a player to wander through, and to choose locations for the player to reach.

And by the end of the game jam I realized that instead of hand-coding it *which I had doe before) I really needed to write a program to generate the code I had previously written by hand.  That may become my next project -- to proceduraly generate the procedural generator.
