Hidden away in a large shed in Cotton in the depths of Suffolk is the Mechanical Music Museum. In a rather obtuse move to keep people away, they only open it on Sunday afternoons for 4 months of the year, but if you're feeling adventurous on a Sunday some time before the end of August then it's definitely worth a trip.
They've got all kinds of amazing things including a Cinema Wurlitzer which is an organ that's connected to a whole room of things that make noise that can disappear into the floor at the touch of a button... awesome. They've got loads of music boxes and pianos that play them selves that they demonstrate for you on their tour, and lots of those huge things that you used to see at the fair ground in Victorian times that are really really loud...
They also have a lot of strange and wonderful things cluttering up the place, the best of which is a monkey with a tail erection.
