I have been playing Minecraft a lot recently. I mostly just dig and explore tunnels and don't spend much time building things to show off. The only thing I have built that is a little worthy of showing off is my Cake Room. The room is meant to be a tribute to Portal 1 and the fact that a cake is amongst the most complicated thing you could craft in Minecraft.

...

It is build mostly out of sandstone and is placed just below ground surface. The floor is made of gold and lapis lazuli blocks and the ceiling is diamond and clay blocks.

The the hall way just before the room.
