How is Make it Happen implemented?
I read your question differently to Andy.

The MIH itself is simply a civicrm contribution page. 

But there are also MIH 'content types' and the page at https://civicrm.org/make-it-happen is then a View (Drupal) based on the above Content Type and I suspect there is a fair bit of custom stuff happening in that View which means an 'export' of it won't give you it in a box.
