Minecraft Halloween Update - Building a Slip Gate

You just need some obsidian and flint/steel. Make a 3x2 door frame out of the obsidian and light a fire at the base. A shifting purple portal will open up. Stand in it for a second or so and it will take you straight to hell.(minus rendering time)

The hell world looks a bit spooky but you don't see any ghosts in this video, just a huge pit of fire and lava.
