"If you could have any superpower, what would it be? (You can't say the power to get more powers.) If you're like me, it'd be the power to fly. Unfortunately, I'm not a Superman, Neo, nor a bird. I'm a software engineer at Yelp; I make things happen by writing code. So I started to write code that tricks me into feeling like I'm flying. What I ended up with was a Mac app that allows you to control a quadcopter by flapping your arms like wings."
