Displaying A Video Game Collection

So I've started to mass a pretty decent video game collection and I was wondering if anyone had advice on a good way to display them. I'd like to display the boxes so that's pretty easy to do. But I have some loose cartridges (NES and Genesis mostly) that I'd like to display. Any tips or items to display them so they don't get dusty or anything. Also show some pics of your collection if you want, I'd be interested to see them.

If I had money, I would get ones like these.

@i_stay_puft: Speechless.

@raindog505: @rickyyo: The feeling of knowing you can never scrub this game off your xbox live achievement list haunts me forever.

@coafi: The top one is a little bit crowded don't you think? I'm thinking more display less library bookshelf.
