Each of the seeds given has 65535 matches for a total of 131072 seeds which will give the same results; also, for every other seed there are 65535 other seeds which will have the same caves, as well as the same terrain (where biomes match) and even villages and other structures, down to trees and ores, in the same places (again, if the biome matches). This is because only the biome generator, which uses its own custom 64 bit random number generator, is able to use the full 64 bit seed value; everything else uses Java's built-in RNG, which only uses 48 bits (this may also apply to other versions as well since most common languages do not have 64 bit RNGs of the sort that would be used here (the biome generator is based on the MMIX generator listed).
Here are a couple threads where I discussed this:

http://www.minecraftforum.net/forums/minecraft-discussion/seeds/2557524-a-very-strange-seed
Note that only caves and mineshafts are affected by the repetition bug since it is a result of a multiplier value being set to 0 and they are the only ones that use it, at least directly (the game derives a unique seed for each chunk by multiplying the x and z coordinates by two numbers derived from the world seed, and either (but not both) can be 0, resulting in the corresponding coordinate having no effect on the chunk seed. Villages and temples use an additional algorithm, which is immune to this bug, to determine where they are located within a given 32x32 chunk region but should still generate the same if they have the same x and z offsets. Features like trees and ores are not affected at all because the multipliers are made to always be odd numbers, which implicitly excludes 0).
Also, in either case you can find matching seeds by adding or subtracting 2^48; among other things, this is how I found the seed mentioned in this thread (I kept adding 2^48 until you spawned right on top of the cave; you can also use this to find a seed with good caves or mineshafts, then manipulate the biomes to your liking).
In addition, as mentioned in the second thread above virtually every seed has a bug (due to the way the chunk seed is determined) that causes the same caves and mineshafts to generate at sign-reversed coordinate pairs (e.g. 100, -100 and -100, 100), with as many as 1/3 of all chunks matching (when I investigated this further a few seeds seem to be immune and the percentage of chunks that matched was always 1/(3*n); e.g. 1/3, 1/6, 1/12, etc).

To achieve a dreamy feel, you have to stop using blur on the subject image, and start using layers, and effects!

Removal if the repeater does nothing, and the block acts like a power source.
Edit:: No mods at all, Mine Craft 1.6.6

I am wondering if you can take a try, and see what you can do with it ?
Screenshots / videos of your finished work would be great to see.
