Douglas C. Engelbart passed away on July 2nd, 2013. That was two months ago. You know that thing that you hand is sitting on? It has two buttons and a scroll that's probably right in the middle? Well, this guy invented that. Isn't that cool? If he hadn't of invented thte mouse, then the internet might not of ever been invented. I mean, think about it; what if Vint Cerf had the idea to invent the internet, but didn't have anything to control it with? He might've given up. What if a butterfly in Africa flapped its wings? You might not of been born. Boom. Mind=blown.
