How do I randomly generate a grid style island map, given two tile types?
<p>I need to write an algorithm than can assign a tile type (one for water and one for land) to every square in a 100 x 100 grid, and I would like it to generate an "island". Something random, but all the land squares together, and all the water squares on the border. Any ideas? </p>

<p>I have heard of "perlin noise" but I don't know how to implement it to give the result I want. I feel like also my case is probably too basic for such a complicated algorithm.</p>

<p>Thanks!</p>
