Well, that seems easier...

renderContentOn: html

     html div
         onClick: ((html scriptaculous periodical)
             frequency: 1;
             on: #renderNextImageOn: of: self;
             assignTo: 'FLPer'

         with: [html text: 'click to start'].

     html div
         onClick: ('FLPer.stop();');
         with: 'click to stop'.
