Seed

I've had some pretty cool seeds, myself, though I usually use the default generator. Back before 1.8.1, I input that coordinate-looking thing that used to be on Cobalt's website (Mojang - oxeye studios game), and spawned in a hole in the ground, containing a single tree -- not that bad a spawn. My first IC2 game had an awesome spawn, right near a swamp (rubber trees!) containing a ravine (ore!) right next to a desert (sand!), and, well, see the page link in my signature & my avatar.
