If you visit a blog that shamelessly calls itself 'nanopolitan', you would expect (at least once in a while ;-) some nano stuff, right? I think meeting (nay, exceeding!) such customer expecations is easy as long as there are sites such as this that I can link to!
Before I forget, I got the link to that gallery from this fine blog. Oh, btw, I got the link to that blog from the Carnival of Tomorrow, the link to which I got from the Dynamist Blog, which I read regularly. Phew, that was some chain-linking!
Whether you visit all these other sites or not, do visit the gallery and get amazed!
