"It's my take on a snapshot of the moment a meteorite collides with a minecraft world. I managed a mega fail at one point and accidentally set the whole thing on fire with all the lava , so had to start from scratch on the meteorite again." So twice he made this, and I thank him for it.
8. Playable Guitar
http://youtu.be/kGFZ9beEgdI My second favourite, this playable guitar by disco_ (creator of Temple of Notch and Cake Defence) is absolutely immense. Using a staggering amount of pistons and redstone, you can step on individual pressure pads to change the chords that are playing, almost instantaneously. There are 10 open chords arpeggios available, and as the video beneath shows, it's ridiculously complicated http://youtu.be/oAQKKI9OJLg
