Ok, this is a completely different world of miniatures, but I'm sure a lot of you will like this.

Being from Hamburg, I've been there several times now. It's amazing! Haven't been there since they opened the airport and in the video I saw some details that I've never seen before. Think I've got to visit this place again.
If you ever find yourself in Hamburg with some time to kill, go visit it. Make sure to be there early or relatively late. Otherwise it'll be full of people. Last time I was there, we had limited tickets for a guest night. Only few people and the guys there explained everything in detail.
If you're into miniature world design, terrain building, model trains, ... you'll love the place.
