Ill post mine soon. It was VERY nooby like. My first house was made of dirt, then the second, of dirt, and the third, of TONS of cobble. It was a cool concept, but it was made from some pretty crappy blocks XD My cobble tower was made so it reached the max block height (of beta 1.8 or 1.0, can't remember) and it featured glass hanging over so you could "feel death". It also had a suicide tower, tree farm, wheat farm, and pumpkin farm...oh the good old days...

 

Sadly my harddrive crashed and I lost my first world :( It was amazing.. I miss it so.

 

My first first world I spawned and punched a wolf. Istillplayon my Beta 1.8 world <3 first. Survival world. House is made out of dirt, cobble, and planks.

 

No screenshots but it was like this: I joined the world, punched down a tree, killed a cow, deleted the world and went searching for a server :p

 

I got a new computer, but i never new how to take a screenshot back in 1.2.3 and that house in that world was just crammed with junk :p
