The MACHmit! Museum for ChildrenFor the Long Night of Museums we are bringing Paul Klee's famous work The Twittering Machine to life! We're building a giant machine from all sorts of material that hisses, clanks and whirrs. The organist Thomas Noll will make the museum organ twitter and in the museum workshop you can create your own twittering pipe. There are also lots of other things to try out.
