+=========
+ASTEROIDS
+=========
+
+Last week, at work, we joked about creating an Asteroids clone where every
+asteroid had a bug number in it, as a bit of a joke. (Ha ha, every bug you
+kill spawns two more!)
+
+I was bored this afternoon, so here's a port of Asteroids to JS/Canvas.
+
+Now all I need to do is hook in the bug numbers.
+
+
+Gameplay
+========
+
+You're the triangle in the middle. You want to destroy the circles. You have
+a gun (spacebar), some thrusters to turn (left and right arrow keys) and an
+engine (up arrow key).
+
+Remember, it's kill or be killed out there.
+
+
+Rights
+======
+
+The name *Asteroids* is, as far as I know, still property of Atari. I mean no
+ill-will towards Atari by releasing this code. Frankly, it's a poor 
+substitute for anything resembling a real game. I just wanted to see if I
+could do it.
+
+If anyone from Atari asks, I will gladly rename and/or remove this code. But
+since there are so many *Asteroids* clones as it is, and the original was
+released in 1979, and it was kind of a copy of *Spacewar!*, I doubt they'll
+mind too much.
+
+
+Strikes me as funny...
+======================
+
+The original *Spacewar!*, one of the earliest (if not the original) computer
+games, took `200 hours to code <http://en.wikipedia.org/wiki/Spacewar!>`_.
+
+This probably took me 6.
+
+I am so glad we've moved past the PDP-1.
