Here's some really messy code which I didn't bother to write a class for. I should've at least written array, but didn't do that either. Nevertheless, it's a good mimic of NED's very basic tiling system. Press 't' and place tiles as you normally do. Dashes indicate a break in the larger program for individual files.

File/Tab One:

boolean filled = false;
boolean square = false;
boolean triOne = false;
boolean triTwo = false;
boolean triThree = false;
boolean quadOne = false;
boolean quadTwo = false;
boolean quadThree = false;
boolean curv = false;
boolean curvTwo = false;
boolean tiles = false;
boolean objects = false;
boolean mines = false;
boolean gold = false;
float y = 0;
float x = .1;
int counter = 0;

// TO DO: 
// Convex hull with each tile, save the curved concave
// boolean array for better organization
// eventual tile class
// Fix gridding issues
