When I'm not working on my own blog —which, let's face it, is most of my time— I read some blogs by other people. One of them recently had something which I can only characterise as impressive. Take a look at this. This is a post by Ysaneya, who is working on an MMO space game, Infinity. His posts are almost always impressive, but when it comes to a procedurally generated galaxy... wow.
