Clone of diy.despair.com

I need a clone of this site: [login to view URL] should preferably be in flash (but if you can do this in another format let me know) and have the same functionality, but also include options to share on facebook, twitter, myspace and integrate the 'sharethis' module. Also users should be able to email the creation. Each time a user creates a new poster the site will create an seo page with metadate title tags (this is the page that will actually be shared on fb, twit, etc.)
