Wii Wii: a video that has to be seen to be believed

It seems even blogs take the day off on memorial day because there are hardly any updates on the Wii blogosphere. The only exception would be this, a video that is mindboggling in it's construction and deserves to be seen at least once. It's kind of hard to explain what it is...okay not really, it's a level-editor Super Mario World thing but it's best to watch without any preconceptions (Also it's longer than 10 minutes but it won't seem so).
