I love Dr. Horrible. I hope they make more Dr. Horrible soon.
I was driving up Sand Hill Road earlier this week and saw someone riding a cool contraption that looked a bit like a bike but clearly wasn't a bike. As I passed the rider, I checked it out and it read "Elliptigo," so I went home and looked it up online. Turns out it is a new vehicle (not yet on the market) that is a cross between a bike and a elliptical trainer -- thus, Elliptigo. Here's a video of the Elliptigo in action. It's very cool.
