Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days. We see a lot of crazy stories here at Engadget, especially when we spend our week poking around in dark and scary corners of the internet specifically in search of them, just so you don't have to. We consider it a service almost. One that we're delighted to provide, we must add. When else would we be able to share such delights as an astronaut triathlete, soft, color-changing robots and a recent response to a thirty-year-old alien broadcast? Exactly. This is alt-week.
