turbo mode (shift click green flag) when the world is done, use left/right arrow to rotate it.
I got the idea from AchillesX and I decided to make one for myself. I did not get any scripts from him though. UPDATE LOG For some reason, versions 1-1.0.6 no longer work. v1.0 release v1.0.1 added caves v1.0.2 added grass v1.0.3 added better ore generation v1.0.4 added transparency v1.0.5 added starting elevation and decreased lag v1.0.6 added coal, emeralds (only spawn when steepness is 3) and cacti (cactuses! :D) v1.0.7 made a somewhat operational rotation mechanism (ores and grass/cacti don't stay in the same place, but everything else does.) v1.0.8 added space biome as requested by we30. (space biome cannot rotate as of now. v1.09 added texture packs. v1.1 added local save, so you can save a world and see it later, but other people can't see it.
