Vox, a new blogging service from SixApart, just released a Chicago skyline skin, which you can see on my silly little test blog. Obviously done from memory, since the east-facing view of the Loop prominently features the CNE building (which can't be seen from the other side of the Loop) and only a few recognizable buildings (Sears Tower, Hancock, Prudential and Aon). At least they tried. (If you'd like a Vox invite, let me know -- we've got four to give away.)
