Sky dimension

The Sky Dimension (otherwise known as the Floating Island Dimension) is a work in progress by Notch. It "performs well, [but] looks ugly". It is now a confirmed update.

The Sky Dimension was first announced after Notch played spleef against @Evil_Notch (video is on twitter). It was probably made to be like a "heaven", since the "Evil Mojang" team declared to Nether to be "hell".

Other Info

 * The "Sky Dimension" might have been inspired by the Aether, a un-released mod, creating an alternative, heaven-like world.
