I loaded a random seed last week and found this seed, which is 409310003
You spawn on a peninsula of large land mass with lots of islands just offshore. In fact, I found three land masses, and each had a number of islands just offshore. Not sure if that's normal for this version but I thought its worth pointing out.
Going to the east of spawn you find a few islands in the middle of the ocean, but there's also an ocean monument.
Going south of spawn is nothing interesting, just an ocean with islands until you find another land mass of the same biomes as the one you spawn on.
To the west of spawn is a mixture of plains, extreme hills, roofed forest, forest and birch forest. The biomes not too interesting but there is a lavafall to be found which you could make a neat decoration from.
The best direction to go in if you want to see what makes the seed interesting is north from spawn. You need to cross the entire land mass you spawn on first (a small ravine on the way, but its not an extreme one its like the ones on other versions), then you go across the see until you find an iceberg around some frozen islands, not far behind which is a frozen land mass of ice plains and ice mountains. Near the coast you find another ravine, same type as the one on the spawn land mass. Go abit further and you come across this weird hill, where there's an area under it which has grass in it. This seems to be the perfect place to transform into a house. Go through this and you'll find an igloo, which has a basement. Go past this igloo, then you'll see a cold taiga biome, which to the right of it is a village with some good loot, but to the left is an ice spike biome and an extreme ravine. Yes, the type that goes down to diamond level from the surface.
