Btw, I have already written something similar in perl.
I had to generate the sequence of (x,y) coordinates in spiral,
something like this:
0,0
0,1
1,1
1,0
1,-1
0,-1
-1,-1
-1,0
-1,1
-1,2
0,2
1,2
2,2
2,1
2,0
2,-1
...
This was for an internet game.
I wanted to discover the
islands on a map with a ship in some order.
This order is good becuse this way the ship travels
only 1 units of distance in each step, so the discovery
was fast, and I discovered the islands near my island
first (as that's where the center of the spiral was).
Bots have since been banned in that game, so I have
deleted the code. Sorry.
