I searched for signature scanners four days ago, now every time I hit a site with AdSense, there’s signature scanner ads. And what made me laugh was the ‘related’ ad for "The Pen That Went To The Moon"
That one reminded me of an old joke from the seventies, how NASA spent hundreds of thousands researching a ballpoint pen that worked in zero gravity. The Russians used a pencil.


Pretty sure the space pen versus pencil thing has been debunked, but it’s still a great story.
