Disclaimer: I didn't know there was a tutorial on this prior to making it and my method is completely different. Make sure to head over to cg.tutsplus.com for some great tutorials including another method of creating this including some compositing in photoshop.
There is no audio since I wasn't in a spot I could record audio.
I made this 'cube world' scene my first time in around 10 minutes, but rendering took about 3 hours. The upsides and downsides are there, the polycount could be cleaner and could have cheated in some spots but I'm very happy with what I've got and the render times don't bother me because it's just a still image.
Hope you liked it
