Category template with subcategories and their products

So basically what i need is,
For example we have electronics category, inside that category we have TV, Speakers and Cables.
When i enter electronics i want to see all products inside its subcategories but with titles of those categories. Here is picture example: http://imgur.com/ruzd26f, if anyone has done anything like this, please write your solution.

Hi

We're currently putting something like this together. I'll let you know the details when done. Obviously if anyone else has done it, would be glad to hear also.

Thanks, Cheers Richard
