I was just browsing the Minecraft seeds thread over on the forum, when I saw that one enterprising chap has set up a blog dedicated to the cataloguing of the best of the seeds. He’s not alone, as Comrade Nullpointer points out, there’s also a YouTube series dedicated to excellent Minecraft landscapes, and I’ve posted a couple of those videos below for your
topological topographical delectation. Lovely. Update: here is another seeds site.
