For all you video gamers, I recently installed one of those pivoting mirrors onto my helmet, and it feels oddly natural having an image of what's behind me in my upper left field of vision. I feel like I need a compass on my lower left now, some kind of health reading on upper right, and maybe a target crosshairs in the center. Maybe I can use a laser pointer?

I'm thinking I should get one of those kids handlebar thingies that make laser and gun noises so I can blast pedestrians as I go. Any other ideas?
