Suggest me some (design related) place to visit in Europe.

Hi. I am industrial design student in Korea. I almost finished my university course. I am going to start to work from January 2006. Now I am planning to visit Frankfurt, London, Prague, Milan, Rome and Florence in Italy this December. And I guess I can’t go to travel next 3 yrs. So, I want to make this travel… so special. If it’s possible I want to visit some ID School, studio or museum. So… Please give me some tip. And!! I am happy to hear any nice (non-design related) place to visit.
