RE: Sanfilippo collection automated instruments

Good heavens. I am in awe of the absolute beauty of this home/ museum. It looks like something straight out of an animated film. The ingenuity is absolutely mind-boggling! Some people throughout history have been blessed with the minds to create and engineer way beyond the average person. It makes one wonder. Is it just up to IQ or is it down to belief in one's self/ self-confidence that allows this kind of mental space for creativity and ingenuity?
