Not quite. Code elements are still being directly referenced from
within the markup, ie. @name and @articles. In Amrita you don't even
have that.

  <div id="user_admin">
    <p id="name">name here</p>
    <ul id="articles">
       <li id="title">title here</li>
    </ul>
  </div>

Then in code:

  if @user.admin
    data = {
      :user_admin => {
        :name => @name
        :articles => @articles.collect { |a|
          { :title => a.title }
        }
      }
    }
  else
    data = { :user_admin => nil }
  end

Amrita uses the data structure to determine the layout structure.
