Subject: museums that you have especially liked
Having advertised Duesseldorf as a cultural mecca, I shall now undo all the good work by suggesting the Plastic museum. It is a very small museum with constantly changing exhibits on the wonders of plastic. It is also techincally free, although to get to it you have to go through an art gallery - the excellent avant garde NRW Forum - which most assuredly isn't free. German sportswear manufacturer Adidas-Salomon seems to basically permanently sponsor the plastics museum. It takes about 10 minutes to go round if you read all the blurbs!
