German firm builds gorgeous little engines

German engineering firm Böhm Sterling-Technik (who I've only just discovered) have released a series of little engines which run on ethanol, and are engineered with extreme precision.

Pictured is one of their larger examples 'Classic Smoking'. Although they don't perform any function, they could become a component in another project (such as a funky, geeky clock) or as ornaments in a modern home.
