ClickClack’s earliest post on Geekhack was about his impressive keyboard collection (250+) and how he likes to disassemble them to examine various switch types. He then proceeds to post a photo of himself holding a bag (unfortunately, the photos are no longer available on geekhack, but you can see it above), and asks people to guess how many keys on various keyboards are contained in the bag. The answer is 6,968 keys from 67 keyboards, and the prize that he sends out is a red Clack Skull prototype, the iconic sculpt he proceeds to sell in 2010 and beyond under the Clack Factory brand.
