The Meaning of Life, the Universe, and Everything.
Know of any good ones? I know two, the first; Coffee first letter capped, rest lowercase- huge clift in middle of map, seas on either side.
Second; (sorry, not allowed) (no spaces in between letters, all lowercase, excuse the language) but it is a great seed, there are great land features and the best part is lava which you can experiment with.
I tried out all those seeds, and they are pretty cool (not allowed either; also, gross!)" without the quotes. Sorry! I am not really that perverted, I was just bored, sorry if it is kinda gross T~TAnyway though... the seed features a BUNCH of floating islands everywhere and is really cool!
Pardon my language, but here are a few cool seeds I came across:
****ingseed- Really tall mountains with a HUGE overhang and a strange bald spot that sort of looks like a dried up river.
0123456789- An odd bald spot near spawn and goddamn weird patterns in the ground.
badword- Has a little of everything. Overhangs, a big and deep ocean (good for underwater bases), some land too.
terribleseed- All I have to say: "two individual floating grass blocks right at spawn".
