Norwegian Museum of Science and Technology

The Norwegian Science and Technology Museum is a full-scale, hands-on museum with dream exhibitions and a large number of activities on the history of video games. Hundreds of games are played for free. Adults and children are also great.

It's a really great museum with many things to try by your self. Unfortunately at the time we where there many sings and descriptions wasn't in englisch. And you have to travel a long time by public transport from the city to the museum (but you can see many parts of the non touristic area of Oslo).
