Change the boring Index of/.... page?

I am setting up a private website on my LAN at home to share documents on but would like to change the boring Index of/ Documents page(in my case).

I can get as far as having the differnet folders listed on the home page but when I then click on one of these folders it comes up with the boring white background, sans serif font. I was wondering whether it is possible to have a good looking page with the files not folders listed and when clicked on download them and not open up the boring page! Many Thanks
