Here is our suggestion for what to do with the
program, below. Move your mouse somewhere close to the top-left corner in the black space,
click and hold it clicked down, then drag it down and right, all
the way close to the bottom-left corder, and finally release the
button of the mouse. You'll see a white rectangle being formed
while you drag the mouse. This is your "selection
rectangle". You can do a number of things with this
selection rectangle, all of which are possible if you click once
on it. Go ahead, click once anywhere within the selection
rectangle. You'll see a menu popping up, with one of its buttons
in the middle saying: "Fill with random cells" and a
percentage (50%) right next to it. Click on this button. You'll
see the selection rectangle being filled randomly with red cells.
Finally, click on the "play" button (), and watch what happens
to your randomly filled rectangle.
