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.
