Here's a helper method I use with Camping.  You can pass in a simple  
array if your value matches your display text like ["value1",  
"value2", ...], or nested array pairs of [ ["value1",  
"display1"], ... ] if they don't.

   def select_form(action, label_text, field_name, option_list,  
button_text = "Submit")
     form :action => action, :method => "post" do
       label label_text; br
       select :name => field_name do
         option_list.each do |value, text|
           option(text || value, :value => value)
         end
       end
       input :type => "submit", :value => button_text
     end
   end

Your example above would look something like:

   options = [ ["marvin", "Marvin the paranoid Android"],
     ["arthur", "Arthur Dent"], ... ]
   select_form(R(MyController), "Select a hitchhiker:", "character",  
options)

It should also be easy to extract just the <select> portion.  In fact  
I think I'll do that on my end too...
