Want an Idea to Create a SharePoint site which demonstrates all the available default WebParts in SharePoint on a single site

I wanted some of your Inputs or Ideas as i need to show all the available Web Parts in SharePoint 2010 and their use. I wanted to show all of them or most of them in a single site collection.

To be more Precise.

I wanted to ...

1. Create a new site collection.

2. Demonstrate or use all or most of the SharePoint 2010 Web Parts which are available for use in the new site collection.

3. Show the working of every Web Part onto the newly created site collection.

4. This is required to give an overview to our marketing Department of what is achievable in SharePoint with the Default Web Parts

Please Help guys about where and how to start for the same. I understand this might be an out of context question. But you never know when and what kind of requirement would arise in future. After i finish with my solution i will add my solution to this question so that others with similar requirement can benefit out of this.
