I've long had a fascination with Rube Goldberg machines for which I blame The Incredible Machine. The formula for a great Rube Goldberg machine – at least, in my opinion – is simple: the bigger, the better. As this video from Seiko demonstrates, however, complexity often trumps size.

An advertisement for the Japanese watch company, this miniature Rube Goldberg machine was crafted using 1,200 individual mechanical watch components with some as small as 0.7mm across. Sure, it's a bit disappointing that human intervention is required at times, especially when it seems a mechanical workaround could have been used, but it's neat nevertheless.
