This morning's prompt is 'celtic spiral'.

I was too tired to get to anything last night and had to come in early this morning.

Random edge fill will require a list of edges to potentially add to the land. I should do a list for land and sea for completeness, but maybe not. The page randomly selects an edge index to grab, splice out of edges, find new edges, draw as land and add to total land area. I can seed to process will random land quads and see what comes...

Subdividing my quads is also coming along.
