Ever wanted to throw everything in a pot and have it spit out ready-made meals? that's what the cooking pot is for. This advanced multi-purpose pot concurrently prepares meals from ingredients inside it employing a sophisticated and efficient heuristic algorithm for determination of recipes. Didn't understand any of that? it's basically a fancy way of saying "it can read your mind!"

Many new redstone devices were added to help make a Turing-complete experience a little smoother without replacing it with dumbed-down turnkey black boxes.

The Ruddimeter was introduced to make it easy to read the precise signal strength of redstone at an exact position.

Given some pre-configured Internet radio stations (supporting SHOUTCAST or playlist format), play music directly in-game for you and your friends the same way a juke-box works, but instead of using discs you use tuning crystals.
