Editor's note: No joke, it would be really cool to have three mechanical spider arms that you could use to see around corners and maybe to get the dishes done faster or to text while driving without putting your life in danger. Then, lest you look funny, you can conveniently store them in a golden circle on your back! Well, we can dream, right? And we can encourage our superhero dreams by getting a different Iron Spider wallpaper for every day of the week. Try it!
