The seed i have found is a very interesting/amazing map. I found it spontaneously because I felt like typing my screen name in the seed generator. I soon discovered I found a great seed, but not at first. Here are all the things that make it special:

1. You spawn in a Taiga Forest (not too special).

2. There are many different types of biomes all close to each other except swamp and tundra biomes.

3. There are cool islands on the top of the map.

4. And finally, the thing that makes this seed so incredibly special, is that there is a Mushroom Biome. Within swimming distance of spawn. The island has cool cliffs at the front and nice "flat" area near the back. It is also fairly large.

The seed is: Pvviolinist

Hope you enjoy it :)
