kamigawa series land artwork

most people didnt notice that the land from the kamigawa block of magic the gathering went together to make a larger picture. i first noticed it by looking at the island mana you can easily see the waterfall around Minimo academy. anyway when i saw this i looked at the other ones and they matched up as well so i cut out the pics from the cards and put them together. apparently the land from lorwyn wich is one of the newer blocks also does this with the land. i'm curious as to how many people actually noticed this
