Unique Inventions of the Wizarding World

There are many references throughout the canon of unusually brilliant wizarding inventions like time-turners, sneakoscopes and spell-checking quills. But none of these are truly one-of-a-kind objects! The first actual unique object we encounter in the books is Dumbledore's deluminator, though it isn't until Deathly Hallows that we learn of its true uniqueness.

In this very participative program, we will work together to compile as complete a list as possible of inventions and objects that do in fact seem to be one-of-a-kind, as supported by canon. Artistic interpretation (in clay and drawing) will be encouraged! Laughter is guaranteed!
