My goals for Quilt #1

My goals for this Quilt are to learn more about stitching adjacent elevation maps together, and to run a fun, somewhat larger collaboration than before.
Take a look at our toe-in-the-water effort, Quilt #0. Two things are obvious:
One, it's just a collection of unrelated terrains, with no coherent overall shape. (Of course, we didn't even try for that.)
Two, the seams are funny - definitely an area to concentrate on.
Those two areas are what I'd like to explore in this Quilt. Hopefully we can get the seam thing under control so we can go on to bigger and better and more creative things in future quilts.

Approximate Sequence of Events

1. Signups + Discussion Over.
   This is when we can discuss what the island will look like - where we'll put cliffs, beaches, mountains, bays, etc. I'll put together a plan based some distillation of those comments.
   This is also when I figure out how many participants we have, and hence, how big the island will be.
   Keep checking in here, and email me any comments you may have.
2. First squares
   The first 25% of the participants will create terrains according to our discussion of the island's look. Each terrain will be a piece of some larger landform, so the edges will look "sliced off". However, no edge matching needs to be done yet.
3. Second squares (Mostly Done now)
   The second wave will be 50% of the participants, each of whom has two edges to match to the first squares, which by this time are all submitted and posted.
4. Final squares
   The last 25% will have the task of making terrains which match on all 4 sides.
5. Finishing up
   Any missing squares get created, then I piece the whole thing together and render the final image.
