This is a really cool creation which can be used for building your own animations in Minecraft. At the same time it's a lot of fun it is also a great learning tool for command blocks if you choose to examine the creation closer. If you don't have the time to build your own animations then there are two awesome presets which you can play.
How does it work?
There are two preset animations which you can play. Simply select the animation which you want to play and then press either of the two buttons (play once/play on repeat) in order to set it in motion.
You can also build your own animations. This is a time-consuming process but I did try it out and it worked without any problems whatsoever. There are 8 different frames and you can build pretty much whatever you like here as long that you make sure that something is changing in each frame.
Important: This map requires version 1.0.5 (or higher) for Minecraft Pocket Edition! Android users can sign up for the beta here!
