If you have not seen this amazing wonder that is over 200 years old, it is a must see. Created by James Cox, an inventor, jeweler, goldsmith and an entrepreneur in the 1770's. Rumor has it, It took a Russian engineer 12 years to assemble the dissasembled clock once it arrived in Saint Petersburg to join the collection.
If not in person, then at least youtube.
