[Rails 3 resource routes with dots; or, how to make a Ruby developer go a little bit insane Virtuous Code](http://devblog.avdi.org/2010/06/18/rails-3-resource-routes-with-dots-or-how-to-make-a-ruby-developer-go-a-little-bit-insane/)

I ended up going with this code:

    resources :top do
      constraints id: /[^\/]*/ do
        resources :crazydots
      end
    end

But yeah, the basic idea is solid. Thanks to avdi for venturing into the madness!
