Notch Working On Minecraft Sky Dimension

All this work Minecraft developer Notch is still doing on his game is making it very difficult for me to maintain my mental image of him spending his days nibbling on a forest full of 5lb gummy bears. The latest revelation is that he's building a "sky dimension", which you can see above and in the gallery after the jump. How will you get there? What purpose will it serve? What happens if you fall off? We have no idea. But it's looking pretty.

I'll admit to being a little underwhelmed by this, seeing as floating worlds were both already present in Minecraft and expanded on in numerous mods. Then again, they were expanded on in mods because they're awesome, and deserve to be expanded on. Hm.

At least, as I said, they're pretty to look at. With any luck there'll be special blocks that can only be found there, too, like in the nether dimension. That'd be nice.
