Help-Life simulation program, Graphics help.

I want to create 3 or more creatures and i want to plot there movements on a tiny 2d world.
I think i would do this by creating a underlying grid, and store the x,y coordinates of each creature.
How could I make my form full screen, and generate a flat one color world where i could display some type of picture for each of the creartures?
This is not extremly important for my program but it would be an added + if i could do it. Im trying to make a simple life simulation on the computer.

The easiest way to do this would just be to set your form's WindowState to Maximized and its border to None...that'll give you a big gray background
