Oh, I so wish there'd be paint to colour anything. I think that's one of the things that's sorely missing, at least for creative purposes. I kind of wish I could put down wood or anything and paint it the colour I want it. Seems like it would be simple enough, as we already have dye.
One of the advantages I realized I had was that I don't have to worry about endermen, being out in the middle of the water.
Btw as far as the dimensions go, it's approximately 236 meters long.
