"DrStonegarden" (minus the quotation marks) will get you a frozen wasteland; pine trees everywhere, a completely frozen ocean, snow everywhere, etc.
After experimenting, I believe it is a fixed spawn seed, so the first sight that should greet you is the sun rising over a little chunk of land in the frozen sea :biggrin.gif:
Mine (zotobom) is goddamn awesome! Floating islands,huge caves and stuff! AWESOME! And dont forget the epic mountains! Dont have time now to make pics,maybe tomorrow. I actually recommend you guys to also use it. Its awesome.
Apogle was ok If you wanted to expore a desert.
I spawned on a small island with a bridge to mainland.
At first I was like "Aw man this Stinks!
Walked 10 blocks and found a lava pit and water pit 5 blocks away from each other.
If anyones seen the WoW video on youtube...youre gonna love checkin this one out. Leeroy Jeenkinns! LOL yep i used it and spawned at the top of a desert mountain and i thought LAME!!!! Nothin but sand and cactus. But a quick 360 and I found sheer drops along some of the mountains which lead me to a pirate ship (mind you i am using Arrrg's Minecraft Overhaul v1.7.3) in a water filled canyon. Will post pics a lil later to show you what Leeeerooooy Jeenkins got me.
"Quesadila" is an epic seed, spawns you close to a zombie dungeon that's covered in sand in a sand pit next to a sand covered skeleton dungeon that look like a screaming creeper with water coming into its mouth.
