Found this on Youtube and thought I'd share it, therefore its not OC, but at the same time, it isn't a repost (I hope)<br />
... enjoy ^w^<br />
Here is the original description from youtube. <br />
A Rube Goldberg machine built in Minecraft. <br />
Save file available here: www.mediafire.com/?2tp1dl6vvzdrw2a This uses World 5.<br />
Because I've been asked this several times, if you want the machine to run correct you must manually reset three water switches and one lava switch before turning it on. A tutorial on how to do this can be found here: www.youtube.com/watch?v=o_IbGccd9No. Each switch should be marked with a sign nearby.<br />
I'm using a customized Painterly Pack You need to login to view this link for my texture pack.<br />
Thanks to /r/minecraft for some of the machines and everyone who made a tutorial.
