Really interesting stuff. Most of the serious bikes shown seem to be in some sense utilitarian- with sport-touring/randonneuring type bikes in the majority there. Quite a few bikes in that category showing thoughtful and tasteful design.
Of course there is lots of the frivolous and "just for fun" stuff too. Stuff like illogically curved tubes, rear dropouts obviously designed more for show than go, frames obviously designed just to be different-looking rather than functionally superior, nostalgic handlebars with the grips parallel to the top tube, busy (and sometimes heavy-looking) ornamentation with no pretense of functionality etc.
My Best of Show: The chrome Herse prototype.
