Hi all.
I've just had a very good experience assembling a
toy I purchased for my daughter's birthday.
Manufactured by a german company named Playmobil,
It is a 'hospital' put together with wall and floor sections using
lugs that are twisted to lock adjoining sections together.
Gotta give the Germans a Hearty round of applause...this Playmobil
stuff is a very
impressive piece of engineering for such a unlikely application.
