After several months of peace, a spider spawned in my main house. It scared the crap out of me.
After watching some Frasier, I was inspired, so I made this:
I call it the Sky Needle. Now I just need to connect its Nether portal with my network and build a path out there, then I'm done with singleplayer until 1.7 is released. But that spider gave me PTSD, so I've given up for the night.
