A windmill in the Museum of the Traditional Folk Civilization

A windmill is a machine that is powered by the energy of the wind. It is designed to convert the energy of the wind into more useful forms using rotating blades or sails. The term also refers to the structure it is commonly built on. In much of Europe, windmills served originally to grind grain, though later applications included pumping water and, more recently, generation of electricity. Recent electricity-generating versions are referred to as wind turbines.

This one can be found at the Museum of Traditional Folk Civilization.

Milka is Kraft Foods' best-selling brand of milk chocolate. It is sold in bar form, in holiday shapes, and in a variety of specialty forms. It was created in 1901 in Switzerland, by chocolatier Philippe Suchard as his first milk chocolate variety.

The brand has a well-known symbol, the "Milka Cow", which is a lilac colored Simmental cow (see also Purple cow) sporting a bell around her neck, usually shown in an Alpine meadow.

Now this well-known symbol has an nice LCD around her neck exposed at Schokoladenmuseum from Köln.
