Because, as you can see, it’s an Angry Birds helmet, not actually one of those treacherous green piggies who keep stealing all your precious eggs. And you don’t want to hurt its lovely creator, Jenn Hall. Yes, I realize I seem to be running with a helmet theme (I previously posted Jenn’s awesome R2-D2 helmet), but can I help it when they’re this snazzy? Apparently not. And, you know, safety. It’s important. Why not be safe and geekishly chic at the same time?
