I’ve been too busy these last two weeks, visiting Oklahoma and then hosting Ken Baker here at Yale, to continue my discussion of Dave Bachman’s SOGs. I’ll try to get back into that next week. For now, I wanted to point out a link to the architecture blog BLDGBLOG about a highway underpass that exhibits non-trivial braiding. Unfortunately, it seems they’re about to tear the thing down and replace it with a more reasonable (and topologically trivial) underpass.
