This is skyland that I made using MCedit and Minecraft. I built an old fashioned house on it, made a river and pond. (cant see pond), put bone meal down for wild grass to make it look even sexier. check out this picture below.
Im continuing and making a Sky Town now (due to some replys), check out this screenshot!
you can do this legit on minecraft but it would take ages. MCEdit saves you about a week of work to like 1 hour.
How I make these floating island, I use forester (in filter section) and make trees sand (mangrove). Then go into minecraft and make the sand fall and go back into mcedit and flip them. They turn out like islands :smile.gif:
