SammyJS json store demo - how to create modal product popup?

Does anyone have an example of making the product details of the SammyJS json store demo show up in a modal plugin like FancyBox?

Here's the block of code from json store - what do I need to do to present it in a model FancyBox?

this.get('#/item/:id', function(context) {
  this.item = this.items[this.params['id']];
  if (!this.item) { return this.notFound(); }
  this.partial('templates/item_detail.template');
});
