This command adds in levitation boots, using some new features of the latest snapshot. When you wear them you jump real high and fall quite slowly. Also if you crouch off the side of a block you will hover over the ground for ten seconds! For crafting look in the source commands. (I apologize if the machine and signs are a bit buggy, it is just a snapshot thing!)
How to install
How to import this command into your world
First, you must give yourself a command block (If you are on a server, you must be 'OP'ed, and have access to /gamemode 1)
To get a command block, type
/give @p command_block in the chat.
Once you have a command block, right click it to open it's GUI.
Now, you must copy and paste the command from your browser into the game. Select the entire command from below, then right click and press 'copy'.
Next, go back to your minecraft world, and paste the command you just copied into the command block. There are a few different keys that may be used to do this, depending on your keyboard. The most common ones are 'CTRL + V', 'COMMAND + V', or 'STRG + V'
Finally, you can press done to exit the GUI, and execute the command block by powering it with a redstone block, a lever, or any thing you can get your grubby hands on. Just make sure you don't place it on top of the command block, or the machine will not be installed!

Crafting:
Combine gold boots, a nether star, and an end rod(found in the new end dungeon!) to get your levitation boots!
