I don't think clam looks "ridiculous", but I suppose we're in to subjective stuff now. :)

In principle this isn't really any different from GTK or Qt theming (where it's up to users to go forth and find themes they like, and set the default as desired), but in those cases you tend to get themes packaged up by distributions and GUI configuration support from desktop environments, and neither seems likely to happen for Tk.
