This is a model of the world with the seed 2151901553968352745 found similarly to the pack.png world this seed was found by Tom Lacko and many others starting with the unbblurred version of the title screen in the gamefiles. With these image files the version beta 1.7.3 version was found to be the one used and then the seed was found after using the pattern of clouds in the image and using special image overlaty program and rebuilding the world from that viewpoint the tall grass in the image was crucial in finding the world seed as the grass isnt perfectly in the center of the block but offset which corresponds to world coordinates in game. Also the colors of the grass based on biomes blending algorithm of beta minecraft was used to narrow down the seed value and the position of the desert biome nearby.
